The 200 images belong to the 3,500 the hidden photos taken by Bob Bonis, U.S. tour manager of the Beatles and Rolling Stones between the years 1964 and 1966. The photographs persisted to be private through Bonis’ life and remained concealed in his cellar even after his death in 1992. It was only until five years ago that the photos were uncovered, when Bob’s son, Alex Bonis, decided to unveil 10 pictures every month over the period of two whole years. Sold through eBay’s art and figurines store, the photos are estimated 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 popular charities. The Grammy Museum also offered to provide a certificate of authenticity with each limited-edition print, an act Prem trusts can develop the worth of the shots and make them more significant than their actual cost.
