Dear Dr. Boli: I recently acquired a guitar at a yard sale, and I am convinced that it is an instrument of great value. I found this label behind the sound hole, which I have had my house engravers reproduce as faithfully as they are able:

My question is this: Is it best to sell an instrument of this caliber by auction, or by advertising in one of the better-quality magazines? If the latter, I should very much like the magazine in question to have an international readership and a substantial on-line presence. —Sincerely, Fernando “Ferdie” Sor, Barcelona.

Dear Sir: Dr. Boli has already taken care of your problem and charged your MasterCard account. You’re welcome.
