The GCD indexer notes that this cover has alterations to the faces of Werewolf and Dracula. It is difficult to be certain if the Yaffa edition is substantially different to the Marvel edition due to the reproduction quality, but it does appear to me that the eyeballs on each face are different, and the linework on the Earth in the background also appears to differ. Similarly to query over the cover on Yaffa's Werewolf By Night #8, I'd like to see clearer prints of the Marvel pre-production covers in order to make a firm call either way.
