The 200 images are from the 3,500 the unseen photographs taken by Bob Bonis, U.S. tour manager of the Beatles and Rolling Stones between 1964 and 1966. The photographs continued to be private through Bonis’ life and stayed concealed in his basement even after his death in 1992. It was only until five years ago that the photos were exposed, when Bob’s son, Alex Bonis, decided to roll out 10 pictures each month over the period of two whole years. Sold through eBay’s art and figurines store, the photos are valued starting from $175 for 11 by 14 inch prints all the way to over $625 for 20 by 24 inch prints. They are vended first-come-first-serve in place of an auction and 10% of the profits will benefit the Grammy Foundation, the Grammy Museum, and other renowned charities. The Grammy Museum also offered to deliver a certificate of authenticity with each limited-edition print, an act Prem trusts can enhance the worth of the shots and make them worth more than their actual cost.
