Speaking of black & white and color, there is a mystery about one of the Santo epics, "Santo and the Treasure of Dracula".

It appears that all current videos, including the one released by Rise Above Entertainment (in their "Santo Collection") are in black and white.
But "Santo en el tesoro de Dracula" was a COLOR movie, and was released as such in France, and even the early VHS sometimes surfacing on eBay-France - although in not very good shape - ARE in color.
So, what happened ? and how was this movie when it was originally released - if ever - in American theaters ?
