I am surfing last nite and I see a Gilmore calendar 1941. Seller is a powerseller. The calendar is full pad, mint and desribed as from an estate. Also desribed as 100% authentic. (note they do not say original) They also have Texaco, Richfield, Union 76,I think Chevron and maybe more. While it is not impossible to have a find of salesman's or makers samples I find that assortment highly unlikely. I think they only had 1941 and 1957 and they started at a buck.
