I originally planned to make a handpainted blacklight marquee for the cabinet, but as it turned out, the blacklight marquee looked awful. Mostly due to my complete lack of skill in sign painting. Also, if I decide to try it again later I'll be using 2 blacklights in there for more brightness. One just wasn't bright enough. Instead I took the high res M.A.M.E. logo into Photopaint, cropped it and printed it across 3 sheets @ 720dpi. Much better.
It's sandwiched between 2 sheets of Plexiglas. It's held in place by a Happ marquee retainer, and lit from behind with an 18" flourescent light fixture. The Plexi came with a protective white coating on both sides. I left the coating on one side of the back plate to help diffuse the white fluorescent light.
