As a child growing up in the suburbs of London in the 1980s, Adam Andrusier became obsessed with collecting autographs of the rich and famous - Ray Charles, Elizabeth Taylor, Neil Armstrong, Nelson Mandela and Boris Yeltsin are just a few of the names he collected.
What started at the age of 10 has led to a career as a professional autograph dealer.
Adam is now an internationally recognised dealer of autographs and historical documents, and has worked as an expert authenticator for Christie's and Bonhams auction houses.
He's just released a book, Two Hitlers and a Marilyn, a coming-of-age memoir about autographs, autograph collecting, and celebrity obsession.
