Where to get an odd-sized print made?

[Mrs.Beagle]

I have 2 old maps of the town we live in. They're on a disc, one's a PDF and the other is a JPEG.

I want to get them printed and framed, but they're strange sizes. The closest I was able to get is 16x20 or 20x24, but there's still some of the map cut off.

Anyone know of any places online that will print odd-sized prints? I want them to be nice quality so I can frame them.

Thanks!

They have 20X30 at costco for $8 bucks.
