Layout proof from the estate of Famous Barr department store's graphic designer for the store's newspaper ad scheduled for May 9-10, 1964. 
It features the store's "Miss Beachcomber" and "H2O Oh! Oh!" collection, with an copy about the look. 
Exact measure is 18" x 23.5". 
It feels like poster paper. 
Above the store name is the quote, "We give and redeem Eagle Stamps." 
Great fashion history and retro decor.
