These two McLaughlin brothers- reshaped 5-gallon, water bottles were made for sale for a Southern California chain of stores (Akron Store) that was the forerunner of the current day Cost Plus in the 1960's. Each one is unique. Both bottles were discovered at the far end of the show and I had to carry them about a 1/4 mile back to the car.
The tray-like one is especially nice as the glass is an attractive cornflower blue color. Both will be available for sale at the National only.
