Pepsi war bond cardboard sign

This is a survivor from the Second World War. Cardboard rarely lasts over 60 years and I have seen only one other like it. This was one of two that a Pepsi collector had and finally after years decided to,part with one of them, before it disintegrated. Pepsi double dot sign saying "Buy war bonds and stamps". Sign is about 5 by 3.5 feet, and probably hung in a store to get people to buy a drink.
