Pawn Stars had an episode the other night about someone that bought a Picasso lithograph at a cruise ship auction for $9,000 back in the early 2000's. Seller said COA was never provided--which I found very strange and red flag-ish. Brett "My Buddy the Art Dealer" Maly deemed it legit, though, and valued it at between $2,000-3,000. Rick bought it for $1,500.
