This is super cool pottery barn kids first year frame. My intentions were to put pictures in them but never got around to it. It is silver leaf. I never pulled the frame from the box as you can see. It has a stamp pad, that may be dry. I've had it for a few years. It has opening for:
1 - 4x6
12 - 2x3

Frame is made from solid hard wood and finished with silver leaf. Glass front.
Includes a acid-free mat.
Mat has 13 openings: 12 are 2" wide x 3" high, and one is 4" wide x 6" high.
Spot clean.

It is very heavy and weighs over 5 lbs with the shipping box. Not sure of overall dimensions.
