I recently found these, two blue decks unsealed with card backs that don't match the tucks and one red deck still sealdd/mint. The blue ones both have a Rainbow Room advertising card in them, and it has a distinctively 50's look.
Anyone have a good handle on the deck? New York Consolidated on the tuck, but CDC Co on the tax stamp. Consolidated Dougherty, I assume. 1 Pack stamp leads me to believe 50's as well.
