A Semi-3D moulded plastic whiteboard/sign. This was made for Video Game stores to help display a list of games that are coming soon. Sonic shows off the list, and a real, working neon bar (see it on the corner/side?) highlights it. You are supposed to just write on it with a whiteboard marker. This would be a nice note-place around the home if you didn't have to plug it in/watch out for the hot neon!
What's wrong with it? Sonic only has 3 fingers.

In the gallary you can see a better picture. This neon-bordered board was seen on Retail Display 1, but here's a closer look at it to complete the entry. It has a real light up neon tube in the plastic edge, & fins on the back so it could stand on a counter or fold flat to hang on the wall. The top says "Coming Soon!" & the store was meant to write the names & dates of games on the whiteboard with the enclosed marker. The card on the back there shows an illustration of how you're supposed to fold & use the board, and plug in the neon bit. The art of Sonic shows him with 5 fingers, so why the actual sign is wrong is still a mystery.
