This great antique frame has been brought in to have the rebate made a little larger. It has some nice details, like the offset corners, crisply carved flutes, and some nice compo ornament, not to mention the huge corner ornaments.
I don't really know how you would describe this style of frame, it has elements of Neoclassical, RĂ©gence, Palladian, Empire, and Louis XVI frame styles. So your guess is as good as mine, let's just call it French.
