SPEAKING OF SIGNATURES!
Okay, here goes for whatever it may be worth.
At a Mid-Atlantic Booksellers Association trade book show in Atlantic City, NJ a few years back, one of the publishers I represented was doing a reprint of an old Gertrude Stein title. As a promotional item they did a very colorful and large graphic poster of the book to be handed out at the show. For what I thought was the fun of it, I took a Sharpie felt pen and began writing "Good Luck!" and signing "Gertie" on the posters for the booksellers before handing them out. Of course, GS had been dead for many years. Well, I could not believe the uproar from a few booksellers who claimed they were having a fraud committed upon them. The great majority of booksellers, being in the know, thought it riotously funny and a great gimmick. It certainly brought attention to the book. The story of the "Gertie" posters was retold with good humor many times at future booksellers trade shows. I still think that publisher owes me a bonus for marketing savvy beyond all expectations.
