This is a Superman-Tim postcard sent to Tim club members on their birthday. The Superman-Tim club was a promotion used by various department stores to sell boys clothing. I’ve covered a few of their items, including these Superman-Tim Redbacks and this rare Superman-Tim Envelope, on this site before… there are a number of Superman-Tim items that were released over the run of the eight year promotion that are collectible today, but many modern Superman fans don’t know about Superman-Tim at all.
This postcard measures 5-5/8″ x 3″ and is printed in one color (red) with a nice birthday illustration of Superman lifting Tim and an elephant.
The reverse has a smaller illustration of Superman and Tim, and shows an original postmark date of 1945.
