the cracks appear to be only in the paint. the only place that its hard to tell is on the headstock, but i'm almost positive they're just in the finish.
i'm really not sure what i'm going to do on this yet. i'm going to look to the guys at dean for some help. i believe they made this guitar in natural finish, and its possible that what you see on most of the guitar is the original finish. if so, i'm just going to sand off the rest of the black.
the other option would be a repaint, leaving the signature along, or if somehow possible, some kind of burst coming from around the signature (again leaving it alone).
and i originally didn't really like the headstock, but its grown on me. plus, after seeing the other headstocks that dean used on these in the early 80's, this one looks much nicer.
