Approximately 23.5" x 29.5" sight size; 35.5" x 42" overall.
Frame was in good original condition; all damage seems to have been incurred when it fell from the wall. Frame was delivered with bag of fragments, and additional fragments were loosened/detached during transport.
Detail images below show much of the damage.
First steps will be attaching as many fragments as possible, then seeing what needs to be added.
