This is a little German Coca-Cola picnic cooler that we restored. It was small—about the size of a Progress airline cooler and able to hold about 6 bottles. Unlike the Progress cooler, the lid comes completely off and there are no hinges. “Trink Eiskalt” translates as you might guess, to “Drink Cold”. We’re unsure of the manufacturer or the date, but would guess it is a 50’s piece.
