Hitler "Skull" Stamps

On 5 April 1937, Germany issued a souvenir sheet of stamps in honor of the 48th birthday of Reich Chancellor Adolf Hitler. In the center were four identical dark green 6-pfennig stamps showing the face of the German leader. An inscription at the bottom of the sheet read "WER EIN VOLK RETTEN WILL KANN NUR HEROISCH DENKEN" ("He who wants to save his people must think heroically").
The OSS produced a propaganda parody of this sheet meant to attack and ridicule Hitler and the Nazi Party. One of the earliest mentions of the propaganda sheet appears in Forged Stamps of Two World Wars, by L. N. and M. Williams, Verdant Press, London, 1954:

"The Allied propagandists represented Hitler on numerous occasions as the personification of death itself, and this idea was expressed in several parodies of stamps put out by the Allies during the later stages of the war. The first intimation philatelists had that a Hitler "death's head" or "skull" stamp existed, came when the Roosevelt collection was dispersed. During the second auction a miniature sheet of four, copied from the miniature sheet issued by Germany in 1937 to mark Hitler's 48th birthday and with the same inscription at the foot but with each stamp showing a skull and a row of crosses as the centerpiece, realized 90 pounds.
Extremely rare OSS distributed set.
