Here's the newest poster I framed for myself, picked up at a recent show here in Ashland.
I wanted something simple that wouldn't distract from the art and signatures so I went with a red inner mat, nuetral outer mat (here I tried to match the color of the paper) and a red woodtone frame. The mat borders are 2 3/4", weighted a little extra on the bottom, giving a total size of about 24 x 30.
On a wall with three other posters–all in black frames–the red inner mat and frame really make this piece pop, and adds some much needed color to my living room.
