There would be a few things I would try to see what works best, but my gut says it would be basically the decal on something like a chloroplast sheet or foamcore with glass suction cups mounted to the back, this way it's not just sitting on the shelf bottom, and you're not having to mess with glue or tape.
Opinions?
What about Spaceballs? I would want to get one to go with the Dark Helmet customs.
I'm just churning through requests, most of what Im putting up are what folks are looking for (and paying for). There are requests on the to-do list which are simpler, like the recent GB logo.
