It looks like a poster frame, Walmart, Target and such should have them. The ones for posters are inexpensive but they're plastic. But the stores have upscale ones as well.

a few years ago i found the perfect frame for my best friend and she loved it but her brothers dog broke it and so i wanted to suprise her for her birthday with it but i cant find it, can anyone help me

this is the frame
