1940s Firestone Tires Die Cut Cardboard Litho Sign

This is a 1940s Firestone Tires cardboard litho sign. This is a very rare cardboard sign that I could not find online. Obviously cardboard/paper has not lasted over the years which make this sign even more exciting! I love the graphics! I am thinking this sign was never used, but it shows evidence of aging and wear over the years. From the style of vehicles, I think it is from the 1940s.
