Antique Picture Frame

Today I got an antique frame, like pics of our great grandparents are in. It has rounded corners on the bottom, the top is totally rounded, and it has curved glass.

Now I don't know anything about this, but I think it might be valuable, and I'm wondering if someone can ballpark a $$ for me.

Also, what am I going to do with it? The person in it looks pretty creepy, and the picture has no value to me... does it?

What are people doing these days with those old, old, frames?

Thanks for your input on this. I know I'm at the best place to get the best advice.
