I saw "The Phantom of the Opera" tour in Philadelphia on Thursday. They were selling posters signed by the cast for $60. I bought one. They were also selling printed notes actually used as props in the show -- the notes from the Phantom to the managers, to Carlotta, etc. The notes, which the actor playing the Phantom autographed, were going for $100. Interestingly, the Phantom was played by a cover on Saturday, and I think he was the one signing the notes, although the posters contained the signature of Cooper Grodin, the regular Phantom, because the posters need to be pre-signed.
In the fall 2012 and fall 2013 campaigns, POTO on Broadway was selling a variety of items. In fall 2012, I spent $10 to get my picture taken with the then-Raoul. For $5, they sold pink-ribboned pins (breast cancer) and red-ribboned pins (AIDS), each with the mask logo. Posters signed by the whole cast were, I think, $40 each. At the end of each show, the Phantom (Hugh Panaro in 2012, and Greg Mills, a cover, in 2013) signed one music-box monkey, which was available for $500. I think there may have been one or two other items, but I don't remember.
Audrey, the Phantom Phanatic, who nonetheless would rather be Jean Valjean, who knew how to make lemonade out of lemons.
