1930 THE FIRST NUDE STAMP "THE NAKED RAJA"

  1930 The Naked Raja by the Spanish painter Francisco Goya. Two sets of stamps depicting Goya's work were privately produced in 1930, and later approved by the Spanish Postal Authority.
  Interesting fact---also in 1930 the U.S. Government barred and returned any mail bearing the stamp. This was the first stamp that showed a nude.
