Jeff Jones and his Iguana

 I remember this cover of Nightmare and I always thought that the "attitude" or pose, of the flying Dragon/Lizard, was a bit off 

What I didn't know, was that Jeff Jones had an Iguana, for at least, long enough to use it as a reference, when he painted this cover.

The Internet, is a boon to a comic book/Illustration geek, like me!
