This sticker 1944-45T is the equivalent of the American gas ration stickers issued during World War II to conserve gas.
This green T (Commercial) sticker was issued along with AA and A. It was different from the American versions because these changed every year from 1942 to 1946. The letters were issued based on what the government determined to be the most important rather than a cut and dry catagory.
This T sticker was restored and reproduced identical to and directly from an original.
