John Agnew had never before done a dinosaur (or other paleo-life) mural before,
and his was his first and seemingly last. He was a teenager (I
think), but had done other artwork before. I believe he is/was a
Philadelphia area native. Really neat painting.
The cover art for _The Dinosauria_ features an
image from a mural painted by John Agnew for the Academy of Natural Sciences
in Philadelphia. Whatever the status of the relevant science, the
execution of the painting is exquisite. Still, I've been able to find
out nothing about the artist or the mural except for the little bit of
information on the book's cover, which isn't much more than I've provided
here. Does anyone know anything more?
