I actually have no idea. I have never tried to buy something like that. But, I am handy with a saw and such, so personally, I would make something that fit my needs. It is more impressive to see something handmade then store bought. LadyE
Depending on what kind of racks/displays you are looking for, you could try using something that is not actually intended for displaying matted photos. When I have done shows in the past, I used a pot lid organizer on a table top to hold artwork. It worked quite well and it didn't cost much at all.
Noelle, I was looking for greeting card display racks -- do a search on google for it. I know you can get greeting card racks thru Amazon and there are other suppliers as well. Greeting card rack suppliers would probably have something similar.
Most places I've seen prints being sold do them in bins --
