I don't know who made this frame, but I love it! It has a look of London frame making to me, although I suppose it could have been made anywhere, probably in the last 10 years. I like the stepped Gluck-esque profile, and the combed lines and ripple wave detail in the gesso is really lovely. The finish is distressed bronze powder gilt with fake leaf lines.
I am not sure what style this would come under, I see a mix of Art Deco and Nouveau, Austrian Secession, and Arts and Crafts... Anyone have an idea what this style comes under? An all round great frame.
