Since most, if not all, of the poses are unique to the set they are some interesting cards. I know a few collectors doing the set. They are really scarce though. Interestingly, in the 1953 ACC, Burdick said:
V89 "(50) about 1 3/4 x 3 1/4 proofs. Seen in proof form, possibly not issued." and he assessed their value at a mere .03 cents each.
