These poster rails are made by Parabo Press specifically to hang the posters they print, but there's no law that says you can't use them for your own on-paper art. Magnets hold the wood strips to the top and bottom of the paper, so it's a snap to switch out old artwork for new.
The rails come in 12-inch or 36-inch widths, and cost $20 or $40.
Parabo Press's main gig is making high-quality prints of the digital photographs you send them, and it looks like they do a wonderful job at that, too. Check 'em out!
