My daughter found a large RCA advertising poster from 1968 in her great grandfather's garage. It features a brightly painted pig in a large photo with the following text at the top: Bank By Andy Warhol. Gaudy Savings by RCA Color Scanner. Pretty as a Pigture, Huh?
I don't see it listed on EBay. Can anyone tell me something about it and perhaps take a stab at value? Condition is good... I'm not a poster collector!
