Vintage Metal Photo Frame With Oval Insert

Vintage metal picture frame with oval insert. The frame has some tarnish, there's an old sticker on the side, and the corner is split open a little bit. There was some old debris and a tiny piece of glass inside of the frame. I don't know if the glass came from a corner of the glass on this frame or not. The insert was hard to remove, so I wasn't able to check. The metal is a light brassy gold color with engraved decorative lines. Two-way easel & a hanging hook is attached. The frame is 6"x8" & the oval opening is 6.25"x4.25"
