I've launched with just 16×20" to keep the costs down, but if you're really interested in other sizes, please let me know. It's not that hard to add more, and since these are all 'vector' designs, any size can be printed without losing quality. Send a message with the contact form.
I don't offer frames because it would drastically increase shipping costs and breakages. I encourage you to frame any museum-quality prints like these. Support your local frame shop!
