My wife does craft shows as the Science Bee and she needed a larger display case for her table. This absolute unit is two 2’x4’ pegbaord panels on a hinge:

And here it is in context on the right side of the table. The smaller case on the left of the table was supposed to be a prototype before I made the “real” one. That was many many years ago. I guess it did serve its purpose though since the new one follows it as a plan, just larger:

And, for Ann Arbor superfans, the frame for this was repurposed wood from the old Workantile Phone Booth project!
