This is used Martin Guitar from 1967. I have owned this guitar for several years and played it a lot. 

I would consider it in good condition, there are plenty of small nicks. It has low action and a passive sound board pickup built in. Its attached to the bridge plate underneath. Comes with case. See video for playing demo

There are 3 areas to notice:
1. There was at one point (unsure when) some deep playing grooves filed in on the first frets of the fret board. Does not affect playing and is not that noticeable. I tried to show this in pictures.
2. The body of the guitar around the bridge has a very small bulge from string tension of 60 years. A small bellying is somewhat normal on guitars. Does not affect playing I just want the buyer to be aware - it can affect playing if it gets much worse.
3. The upper neck has lost some shimmer and lacquer because its been played for years. Tried to show in photos, while its unnoticeable in my playing hand you can tell its well played on the upper neck compared to the lower neck.
