Here's a shot of my
bread board style display I use at shows. The panel is held into the frame with screws & wing nuts. I use a magnetic clip to hold my entry sheet and it's a nice way to show off my dash paques as well.
The graphic on the top is cut out of black refelctive tape.
I intend on making another display like this one for my bolt when I get it closer to completion.
Another idea I had for the car board was a similar frame, but made to stick out of the end of an old 500lb bomb fin cap I have, seein as we call it the Black Bomber it kinda fits. Have been using it as a stand for my photo book.
