Wallet Card at a Long Island privilege sign

One thing the wallet card and I have really been interested in finding is old privilege signs - advertising signs with Coke or Pepsi logos that were common in the 1950's and 1960's but are rarely seen today. I have shown a few in the city but this is the first I have spotted on Long Island - this is the Chateau Coffee Shop in Woodmere, across the street from the LIRR station. It appears to have opened in the mid-1970s and the sign almost certainly dates from then.
