Exposition Cancels ~ Rare Exposition Postcards ~ Exposition Postcards by Allen Wright
Note: Except for the Pacific Limited postcard, I have seen only one example of each of these. There must be more out there somewhere, as these do not appear to be one-of-a-kind postcards, with the possible exception of the “Exposition Special” by Lee Passmore at the bottom right.
