Some call Stamp Day for Superman the 105th episode of the Adventures of Superman series because it uses the series actors and sets; however, the episode was specially commissioned by the US Department of the Treasury in 1954 and shown in schools to promote the purchase of savings bonds. So, the piece plays more as propaganda or a commercial than the rest of the series. Also, since it was paid for by government, this episode is in the public domain. Feel free to distribute it at will. Seems like selling bonds to kids is a tough market, but if anyone can do it, Superman is probably the one.
