Hello Clint,
I saw your post over on the game used forum as well. Nice Bo Jackson ball. I have a large collection of Eagles game balls - about 18 right now, and a few non Eagles. I have a couple of game balls in identical design as your Bo Jackson ball - one is a Rams game ball and the other is a Vikings ball, so I am assuming that those teams all farmed the painting out to the same company/artist (one of my balls is mark "The Ball Company)
On a related note, I recently picked up three Eagles game balls from a relative of former Eagles owner Leonard Tose. Tose's story is a fairly sad one in that he owned a huge trucking company and the Eagles, only to lose it all due to a massive gambling problem.
Here are my newest Eagles game balls, as well as the other ones I mentioned that look like your ball.
