Great Vintage Gibson Acoustic. Hard to say if it's an L-00 or L-0. 14 frets clear. No pick guard with no sign of previous pick guard. Bound top and back. plays great and sounds incredible, I've had it for more than a decade and had it checked out and set up by a vintage guitar professional in Los Angeles a number of years ago. I can't find a serial number anywhere. It appears to have been originally all black and the sides and back were stripped and the top perhaps refinished in black. I haven’t altered it in any way. See pics and feel free to ask questions.
