Well, I have good news

and bad news

I tried the jelly stripper that eats away enamel paint. I pretty much destroyed the side art. You can still make out what it was originally, but it melted the original colors together and looks really bad

For some reason, I decide to try the second side. I removed the black and saw that there were some spots where the medium blue came off a little. So, I began scrubbing with the nylon brush. To my amazement, it scrubbed off the blue spray paint slightly. So, I kept scrubbing until it was gone in that spot. I was amazed to see the original art intact underneath. After a couple hours of scrubbing paint, the spray paint is gone and the side art is beautiful

There are some dings in the wood, but overall it's amazing!!!
Oh well, 1 out of 2 ain't bad.
Anyone trying to save their original paint job, use Goof Off and a lot of elbow grease!
YMMV,
