Hello ! I am an amateur jazz guitar player based in Brazil who is collecting signatures from luthiers around the world (and collecting some nice archtops as well ...). The signatures are collected on used, empty guitar string packs - what makes this a really cool collection. So far, I have received almost 100 signatures ... including Bob Benedetto, Buscarino, PRS, Manzer, Monteleone, Pagelli, Collings, Koentopp, Godin, Carbonaro, and many many others. You can see the project at this link below, including instructions on how to ship it. http://www.jazzpion.com/#!the-luthier-project/c1l48 Shipping address: Daniel Melo Caixa Postal 5516 Campinas – SP – Brazil 13.092-972 Let me know when you do it so I can track it. I would really appreciate your support ! Thanks, Daniel
