Here are a few items of interest to collectors... 

The Marabout Key Ring
It was proposed in the first books of the Marabout collection. You had to gather a given amount of coupons from several series and send them to Marabout. The key ring contained miniatures of the first book of each series (there were six of them). Each miniature had the original version and the text of the first chapter of the novel. The Doc Savage miniature was L'homme de bronze. This key ring is very rare nowadays and traded for hundreds of dollars between collectors. 

The Movie
The George Pal movie "Doc Savage- The Man of Bronze" has also been distributed in a french version called Doc Savage arrive. It raised even more deception for the french speaking fans than for the english speaking ones, because the voice dubbing Doc's one had a strong pronunciation default, sounding like "Hello my friendsh, my name ish Doc Shavedsh" (à la Daffy Duck). It was hard to understand that such a perfect creature as Doc Savage, able to almost perfectly imitate any voice, could suffer from that default! 

The movie is available on video tape, but is hard to find, even in large video clubs. It is not known whether the french version of the movie has been played on TV. The movie poster makes a nice collectible. It is not known whether other promotional material is also available.
