Dear T Rex cover

My computer had a nervous breakdown in March and I thought I’d lost all my images from this title, Dear Tyrannosaurus Rex.  Here are some that follow the development of the cover art I found on a disk.

The story’s about a girl who sends a T Rex an invitation to  her sixth birthday party.  The first sketch is for front & back cover, showing T Rex opening the invite in his museum.  Next is the painting with more background on the left side, including the security guard.

The art director wasn’t happy with this image, and suggested something simpler.  Here’s the sketch and the painting.
