In 2003, Alfredo Martinez was jailed for faking drawings by Jean-Michel Basquiat. While in prison, Alfredo drew images on any paper he could find, with any pen or pencil he could get his hands on. He would then color his drawings with coffee grounds, sign the artwork with both name and inmate number, and ship them out of prison by labeling them as legal documents. I find his story facinating
and his drawings
even more so.
