Putting together some trophies for a small show coming up in June. Keeping it low-buck and fun, and not taking anything too seriously (which ruins everything). Here's an example. Frankenstein glued to a plank of wood, and awarded to the car with the "Best Flathead". You get the idea ...
Have a ZEROX machine at show where each participant can print out on high quality paper their own "BEST OF SHOW" or other "winner" awards category certificate, if they want one. Price: $10 each. Picture frames for certificates would also be available at $10 each.
