Carvings of birds, especially ducks and other wild species, are collected by those who consider the best examples to be art, while other examples are to be used as decoys when hunting.

While both types of decoys can be found at antiques auctions and shops, most are sold in auctions or shows that specialize in decoys, wood carvings and related pieces. The best of the 20th- and 21st-century carvers are famous, and collectors can name the most talented.

A stone carver named Charles H. Hart (1862-1960) hunted and made decoys for his brother and friends. At first Hart specialized in just a few species, including black ducks, Canada geese, goldeneyes and mallards. About 1900, he started making a stick-up black duck that had detached wings that flap and a head that could be turned.

Hart was soon selling his birds to stores in Boston. In the 1930s, when the country was fascinated by the explorations in Antarctica, he began carving penguins. Most had applied flippers and color showing at the neck of the black-and-white birds. He made them in all sizes, from about 6 inches to 4 feet high.

Today, because of the movies "Happy Feet" and "Madagascar" featuring penguins, there is renewed interest in the penguins and the work by Charles Hart. The 8-inch-high birds have been auctioning for $400 to $750.

Drop-leaf table

Q: I bought a secondhand Ethan Allen drop-leaf side table back in 1967. It's still in very good condition. It's maple and in a typical Early American style. It's marked "Ethan Allen" and "Baumritter." Why Baumritter? And what is the table worth?

A: The furniture company we know as Ethan Allen was founded in 1932 as Baumritter Corp. The owners were Theodore Baumritter and his brother-in-law, Nathan S. Ancell. The company, based in New York City, made and sold housewares and decorative items the first few years. It didn't start manufacturing and selling furniture until 1939, three years after the partners bought a closed furniture factory in Beecher Falls, Vt. The company named its Early American line of furniture "Ethan Allen" after the Revolutionary War hero from Vermont. The company's name was changed from Baumritter Corp. to Ethan Allen Industries in 1972. Your table is an early one if it's marked "Baumritter," but it's not an antique. Still, the table is well-made and solid and could sell for $100 to $250.

Gas ration card

Q: I have a gasoline ration card from July 10, 1942, that belonged to my husband's grandmother. It has a large capital letter "A" and the words "Basic Gasoline Ration, United States of America, Office of Price Administration" on the top. My grandmother's name and address and the make, model and date of her car are written in ink. Is this worth anything or just a piece of the past?

A: During World War II, gasoline, tires, sugar, meat, shoes and other items were rationed. Gasoline rationing began in 1942 and lasted until World War II ended in August 1945. Gas rationing was meant to reduce driving so the supply of rubber and gas could be used for military needs. The car owner received a ration book with coupons that had to be redeemed when buying the gas. A sticker with the appropriate letter was displayed on the car's windshield. Most people were issued the "A" sticker and card, which allowed 3 or 4 gallons of gas a week.

People working in the war effort who needed to drive to work were allowed up to 8 gallons a week and had a "B" card. "C" was for doctors, nurses, ministers, mail delivery, farm workers, construction workers and several other groups, "E" for emergency vehicles, "R" for non-highway farm vehicles, "T" for truckers, and "X" for members of Congress and other special groups. Gasoline ration cards sell for $1 to $3.

Brass Madonna

Q: I have a signed Phoebe Stabler brass Madonna and child statue that was my great-grandmother's. Is this of any value?

A: Phoebe Stabler (1879-1955) was an English sculptor best known for her pottery figures. She also made figures in bronze and stone. Bronze figures made by Stabler have sold for more than $1,000 at auction. A 13-inch bronze Madonna and child with John the Baptist, made by Stabler in 1907, sold for $3,686 in 2012.

Pewter napkin ring

Q: I have a pewter chick and cracked eggshell figural napkin holder that's been in our family well over 80 years. Can you tell me who made it and its value?

A: Napkin rings were fashionable from 1869 to about 1900. Most were made of silver plate, though sterling silver, porcelain, glass, wood and other materials were also used. Silver-plated figural napkin rings are popular with collectors today. Several companies, including Derby Silver Co., made figural chick and egg napkin rings. Most figural rings with silver plating in good condition sell for $100 to $300.

The Don decanter

Q: I'm clearing out a friend's house and found an 8-inch-high black figural decanter. The figure is wearing a cloak and wide-brim hat and holding a red torch. The stopper is the top of the hat. The only marking on the bottom is "Wade, England." Can you give me any information about this decanter?

A: Your decanter is called "The Don," made for Sandeman port and sherry. The Don is holding a glass of wine, not a torch, and he's wearing a black cape similar to those worn by Portuguese university students. The image first appeared on posters made for Sandeman by George Massiot Brown in 1928 and has been used in Sandeman ads and on bottle labels for many years. The company claims it was "the very first iconic logo for a wine." Sandeman was founded in London by George Sandeman in 1790 and still is in business. The Wade group of potteries was founded in Staffordshire, England, in 1810. The pottery still is in business, now as Wade Ceramics Ltd. of Stoke-on-Trent, Staffordshire, England.

Wade made your decanter in about 1960. Figural decanters of the Don were also made by Royal Doulton and Wedgwood. The value of your decanter is about $15. Bottles by the other more famous makers sell for about $25.
