Does this ring any bells?

I'm trying to find something I checked out from a library several years ago. I think the book I'm looking for is vintage and there were color illustrations of monsters found within. I remember one page had the image of a possibly Roman soldier transforming into a werewolf. I am pretty sure another depicted a yellow Mothman with a very humanoid face but with giant red eyes that might have been buglike. The winged cryptid was flying towards a man nearby a tree who could have been a construction worker and he looks frightened maybe using it as cover. I do hope I have given you guys enough to go off of.

I take it this is not a book on movies.

Sounds like something you would find in the Tales from the Crypt books, but those were not in color.
