Art Rescue Organization
I've heard several stories of artists forced to abandon storage units or old apartments in a hurry who had to discard or otherwise leave behind large portions of their work.
Seems like it would be a viable business to form a non-profit organization that could go pick up the art and give the artist a receipt for a donation at some reasonable amount; this way the artist could at least get a bit of a tax deduction for the donation, and, the organization could then redonate the art back to community projects and use it in auctions to raise money for community projects.
