I grabbed my old Epiphone out of the case and took a couple of quick pics. Of course, taking pictures of a guitar to admire it is like listening to the Mona Lisa. Anyway, here it is, forgive the crappy pics.
The back is three piece with a maple center between brazillian rosewood. It's got some well earned dings and scratches, but I wouldn't trade. I play it almost as often as my Collings.
