I have always been particularly intrigued by the poster art of Broadway musicals and how a simple image can tell so much while simultaneously enticing the throngs to enter into the theatre and buy a ticket. In my college theatre management class we examined poster art and how the slightest misstep can be fatal. The original poster for Damn Yankees was simply the title of the show with some pennants and other baseball imagery around it. Ticket sales, despite good reviews, were sluggish. The solution: slap a scantily clad picture of star Gwen Verdon over the title and WAMMO! - a home run. Tickets sales went through the roof.
A few years ago, I had the wonderful opportunity to chat with poster designer David Byrd who, among many other achievements in rock poster design, created some of the most iconic theatre posters including those for the original Godspell, Hair, Jesus Christ, Superstar, Little Shop of Horrors and Follies. Mr. Byrd shared the essentials of great poster: they need to first catch the eye, second establish mood, and third impart a quick message.
