Singled out of the prohibition set 52 Proof is as whiskey is as American as apple pie.The oak tree on the front of the tuck box and seal - a symbol of the ageing process for fine bourbon, matured in charred oak barrels to develop the distinct smoky flavour.This oak motif continues throughout the cards, from the Ace of Spades right around to the back design.While bars before prohibition were predominantly male domains, in the 1920's many women flocked to speakeasies in their best flapper attire.We've taken inspiration from images of the era to design the court cards, the art-deco was very in-vogue at the time.52 Proof.The American Spirit.The true taste of America.
