 ABC's Jim Ryan delves into the art and act of collecting. It's the stuff of fantasy. Discovering a 1951 Hudson Hornet four-door sedan in an abandoned barn. An original 1940 Batman comic number one in your grandparents' shed. Or a Babe Ruth autographed baseball card in your late uncle's attic. This is so amazing. It was almost like a museum. In the attic is where the Holy Grail is. It was baseball cards everywhere.
