Another Picture.

It's Colonial Revival, and technically, it's probably not antique yet, but vintage.

Colonial Revival had peaks of popularity in the 20th century with one around the turn of the 20th (in some regions anyway), one starting in the 1920s because of the 1926 Sesquicentennial and one starting in the post WWII era of the 1950s when people moved out of cities and started buying old houses a la Mr Blandings Builds his Dream House, this one kind of lasted until the Bicentennial.

This mirror looks most like post WWII Colonial Revival to me, probably 1950ish, not the earlier 1920s version. The eagle has a very Deco-Moderne quality.

Thanks! This mirror does pass the antique mirror "key test" if that helps. Any idea as to it's value?

Stuff like this tends to have a value of what someone will pay for it at a given time in a given area, since it's a manufactured piece. Right now the market for colonial revival is not all that competitive, and even run-of-the-mill real 18th and early 19th century furniture can be had for relatively low prices. I bought a Chippendale-style mirror from the 1790s a few years back for a few hundred dollars.
