Jeanne,
I doubt there is anyone in the Boston area who could frame an oval picture. You may need to bring it to Appleton, Wisconsin, where there at least two of us qualified to frame ovals.
Actually, there are probably any number of framers in your area that could help you. It would be nice if one or two would step forward here. Maybe they're shy and will email you directly. Just make sure that whoever frames it has the sense and the means to keep it away from the glass. Your picture may be an unusual size, though there are companies that make reproduction frames in sizes that were once common, like 14x20, and now are not. It's also possible that your picture is convex, in which case you'll need "bubble glass" and a frame that can accomodate it.
Come on, Boston Grumblers, I can't do EVERYTHING for you!
Welcome to The Grumble, Jeanne. People come here for all sorts of reasons, but I'd have to say yours is one of the more interesting.
Ron
