The First Great Serial Spectacle!
Thrilling Strange World Adventures!!!

Wow. This image for the Planet of Peril Flash Gordon serial (synopsis here) is stunning, and takes me back to when I was a young boy in the 1930s and saw posters like this all the time at my local talkie. The fact that I was never a young boy in the 30s makes the poster's nostalgia-inducing power even more impressive.

This particular rendition of Flash Gordon isn't available on YouTube, so click through for the full poster and the fantastic Filmation animated version.
