STANSTED MOUNTFICHET, UK – What may very well be the world’s largest private collection of autographs is currently offered in an online auction that closes on Sunday, June 25. The Clive Bullimore Autograph Collection includes the signatures of around 60,000 different celebrities, amassed by a former stockbroker over a period of more than 70 years. The massive assemblage representing a who’s who of 20th century pop culture is expected to make in excess of £100,000 ($127,600) in the sale, which is being conducted by the British auction house Sworders.
