I was just watching Pawn Stars on The History channel (01/25/2011). A gentleman brought in an actual can that was labeled Can Can Pearls. Believe it was from the 1950s. Not quite as round as a tuna can but looked about 3 inches tall. the pawn shop bought it for $10 and opened it. Inside was a strand of fake pearls. It was 17" long and had a metal clasp.
