What would you do if called upon to produce a giant sculpture in an unfamiliar material - would you really insist on doing all the work yourself?
I would give credit where credit is due. If I (Richard) conceptualized it, and four stone cutters (Rafael, Emil, Hank, and Martin) carved it, then the only proper thing would be for the five of us to sign it. Granted, you have to stop somewhere—the guy who swept up the stone chips every evening would not get any billing, but not to acknowledge and reward the people who actually made the piece, just because I am a promoter and they are not, is just plain sleazy. That said, the fact that we live in a society that rewards sleazy promoters over honest workmen requires that we not be stupid and that we watch our backs at all times.
