Dear Ms Miller,
This is another N.B. Hall. Something along these lines is a possibility, but with a different corner pattern.
In this first picture, the second one in from the outside would be a good choice.
No. 15 CV Panels (Village Series) — examples
This one would look great, too.
No. 15 CV Special Corner (variation)
Below is an Albert Groll. This is a 1″ wide mortise and tenon frame with a 45 degree bevel which is carved. I like this frame for your print. Has the right simplicity and rustic feel and form.
Just showing you this one (a Wm. S. Rice) for the effect of the gilt slip.
I look forward to your reply.
