Robert Blake feels completely comfortable showing his face in public. TMZ says:

He showed up again, explained himself, and said he'd sign them for free. Here's video of the event, where he praises his fans. He still has fans? Who goes somewhere in the hopes of snagging Robert Blake's autograph?

He shouldn't be doing the signings for free; wikipedia says:

Ah yes, those legal issues, which included a trial for murder - he was acquitted - and a civil trial for the murder, brought by his dead wife's children. He was found guilty and ordered to pay $30 mil, although that was reduced by half. Yet somehow he is not a homeless bag of bones. Wonder what his secret might be.
