MCAD's mammoth sale has reigned supreme for 15 years, but lately it's been getting some stiff competition from others that make up in ingenuity and artist generosity what they lack in size. The Soap Factory fundraiser's premise is truest to the spirit of both art appreciation and altruism: Each of 150 donated artworks is 8 by 10 inches and costs $99, and you don't know who created it until after you buy. Now in its eighth year, the $99 sale will be held on Sept. 27. Past donors have included Alec Soth, Frank Gaard and … Steve Buscemi? 514 SE. 2nd St., Mpls.; 612-623-9176, soapfactory.org
