1960s? Double Cola Poster(Litho)

[SODAPOPBOB]

CC1 I'd say that's a major plus toward it being original. Check out this Double Cola poster on eBay that has DC-22 LITHO IN U.S.A. on it ... http://www.ebay.com/itm/VINTAGE-1960S-GROCERY-STORE-DISPLAY-DOUBLE-COLA-CARTOON-ADVERTISING-SIGN-POSTER-/111297893129

Hm Id still like to know what the numbers stand for.

It strikes me as very "deco". Just a comment, not saying real or not but it looks like 1930 art.Was there a deco revival in the 50's or 60's?
