Up for auction here is a rare mint 1940 one dollar carmine red US Documentary tax stamp.  This was the first year for these new stamps to be used.

History:  During the period from 1940 to 1958 the Department of Internal Revenue released several hundred, Documentary, revenue stamps in three basic designs with denominations that ranged from 1-cent to 10,000-dollars and with a variety of different portraits of notable statesmen, each denomination of stamp bearing a different portrait. Almost all of the issues of this period were printed in "carmine" red. The higher denominations of 30-dollars to 10,000-dollars bore a unique serial number as an added security measure. A few reprints from 1917 were also issued during this period.
