This came out of a very high end estate here in Las Vegas. I don't know anything about Stag Beetles - I will leave it up to the experts. IT has been professionally framed. Frame does show some wear in spots and there is some light scratching to the acrylic. I will do my best to answer any questions. Very special piece. I hope it goes to a good home. Measures 19 1/4" x 15 1/8" x 1 1/2".
