I've got my prop collection and some of them are pretty obscure. I'd like to buy some 3 x 5 signs to tell people what these things are.

While I have to believe I'm looking past some obvious sources, all I've been able to find is award plaques and desk signs. I'm wide open to your suggestions!

I have been using these from Office Depot.

5 mins in Photoshop to make the labels to match the rest of the signs in the theater.
