We made several guitars for Santana, including the butterfly winged one dela referred to. We made a replica of one with lots of inlays for a store in Japan (who also bought a replica of Jonsey's Tree of Life bass). Sadly, we weren't very good at taking pictures in the early seventies, so I'll join Michael's lament about the lack of photos in the listing. It's going to be a hard sell without photos, I think.
I saw Donovan at a small club in Cotati when I was in high school. It was a great show, and he played my favorite song of his with a nearly half hour introduction about how the song came about, it was wonderful. He still has that 12-string, but I'm not sure if he still has the 6-strings we made him.
