This is an incredible collection of backstage pass uncut sheets: Bob Dylan (5), Paul McCartney (2), Allman Brothers, Jefferson Airplane (2), Neil Young Crazy Horse. These are pretty much one-of-a-kind (all are different), as they were used to sign off on design approval, some with the actual interoffice signatures. All were obtained directly from Otto Printing and Entertainment, who still produces the passes and tickets to this day.
