April–May 1947, Superman-Tim Club Poster Stamps

The Superman-Tim Club was established in July 1942 through a partnership with clothing advertiser Streeter Blair. Each member received a monthly magazine, a button pin, and an official membership card. The membership cards contain a secret code used to decipher club messages. Unlike the Supermen of America Club, a new card and code was issued to Superman-Tim Club members every September. Various retailers mailed a Superman-Tim birthday postcard and Christmas card each year. Some participating stores offered a free birthday pie.

The Superman-Tim Club distributed eight different sets of collectible "Poster Stamps" from September 1942 to September 1949. The stamps contain messages that are deciphered with yearly code cards. A new stamp was included with each monthly issue.

 The first stamp series was issued from September 1942 to September 1943. Each are numbered and perforated similar to a postage stamp. The stamps could be pasted on the white Superman-Tim Press Card. The 1942–1943 Press Card and stamps do not contain any copyright date. The World War II storyline involves an international spy known as the Brown Scorpion. Stamp #2 depicts a racist caricature of a Japanese soldier.
