This is a metal frame, I believe it to be cast iron because of the weight and the feel of it. It has a light rusty look to it. It has a moon and star depiction. It's a really awesome frame with a glass cover and cardboard back. 5&3/8" T x 5&3/8 W and 1/4" thick except where the moon and stars and the smaller moon are. They are a raised releif pattern so they stick up higher where the big moon is is approximately 3/4" thick and the others right under a half " . it's hard to say exactly because of the shape of it. But it is a heavy frame. The picture hole is approximately 2&3/4 W from one side to the next in the front. So it would have to be a small picture to fit in it. The back side of frame is 3&1/2 x 3&1/2" approximately. Made by welforth, made in china.
