How do you mount/hang your lithos?

[ChefBilly]

I know there was a thread about this a while back, but I can't find it.
I don't really want to matte/frame each lithograph, so I'm curious if someone has come up with a less expensive, yet nice looking way to hang them...

Thanks!

We used (cheap) black thin frames from WalMart and the matte that came with each one. We have them on a yellow wall so the black frames make them really stand out.
