Go to a flea market, or good will , or alternatively, you can just make a frame.

Go to micheals, they sell simple black poster wall frames. They look nice, just simple plastic. I get them all the time if I just need to throw a quick, cheap frame on something. Make sure you inspect it before you buy it for cracks. Also if this is something you're going to be moving around a lot or taking in and our of the frame a lot, probably invest in something sturdier.

This one is $10, on sale for $6
