Tim NewcombThat one pack in the box was opened, supposedly back in 1952 by the boy whose father bought them for him. The claim is that this one pack contained five cards, two or three of them high numbers. It's the only time I've ever heard that 1952 high numbers might have been mixed in with earlier series. It seems plausible enough, but I don't know how Mastro can prove it conclusively without opening more packs, which I guess they don't want to do.
That's what I heard, anyway
