"American Woman" sign

I'm not really sure what this is, but if it's not an antique, it is certainly very old. <br>

As you can see, it is a picture of a woman in back of a large red "A" of the color and font use by Anhaueser Busch. It is mounted directly on an old wooden backing.

The copyright seems to be about 1920 or 1930, and the words "Knapp Co." are on it.

The title is "American Woman".

I thought it might me an ad for American Woman magazine, but, as you can see, the model is rather scantily dressed for the period.

I've searched for hours online and not found anything like it. Even if you don't want it, if you know what it is, will you drop me a line, please?
