Get it done at the frame shop in the rear of the store.
There's a 14 x 18 or get something a little larger and matt it. Or you can get a custom frame
I am not sure. That measurement sounds like an odd size. I have bought all kinds of frames from them. And recently I had a large old picture reframed and it came out beautiful. If you go into their store someone in the frame department is always willing to help you. Trust they have all kinds. I was so happy with what they did with mine.
Doesn't look like it on the website, the closest is 16" by 20" from what I can tell
