The frame pricing will be on the shop site. I'll add them to the main page on the website as it's a good question. Here are the prices. Subscribers get 10% off these prices.
Large Generic: $250
Large Custom: $350
Small Generic: $180
Small Custom: $230
You can see pictures of the frames on the site. (Generic frame is the same across all prints. Custom is different for each print, designed to match the print coloring more closely.)
