Lg vintage mirror/needs rebuilding (20882/Goshen area of G'burg)

This is an old mirror - I have no idea how old - but it's come apart and I don't have any interest in reassembling it. It's heavy, so be prepared for that if you pick it up...it's not the kind of lightweight mirror you'd find somewhere like Target. The photos show the frame, backing, and mirror itself. It's 36 inches wide X 28 inches high.
