Come on Steve, there are dozens of Galleries with signed Morrison guitars to compare it to. This one looks as real as all the others, in my opinion not REAL at all.
I've never even heard of one...not at the Hard Rock, not at the Doors exhibit at the Rock & Roll Hall of Fame and Museum, not through any of the major auction houses. Never.
It's a genuine guitar!! Good color, nice strings, really good neck and pretty wood. Unfortunately someone scribbled something in ink on it. Otherwise an absolutely real guitar. Oh, you mean that wasn't the question?
Excellent question David. Collectors need to know that the shape of the signature has to be correct before you can move forward with any other things that get looked at. Since the shape of the signature is not even close to an authentic example there is no need to see the item in person. It doesn't matter what kind of ink, pen pressure or the year of the guitar, if the shape is not the same as known exemplars we can safely say if something is not authentic.
