I listened to an interview with Jeff gold on KCRW today. Basically he said he is a music memorabilia dealer and someone wanted to sell him their collection. When he started seeing the pictures he surmised they were one of a kind and the world needed to see them and thought a book was a good way to get them out there. They’re apparently pictures the clubs would take of patrons, develop them during the show and then try sell them to you as you left. Sounded like he found the pics and became fascinated with them and started researching. Good for him, I’m more intrigued by this book now.
