A massive collection of Genesis memorabilia, valued at over $50,000, will be auctioned off later this month.

The collection belonged to Genesis fan and biographer Peter Vickers, who died several years ago. Among the items being auctioned off include rare U.S. and Japanese singles, a program from the band’s 1972 Foxtrot tour, and more than 300 other items.

Vickers began collecting Genesis items in the mid-70’s and has even published books on Genesis collectables. The collection will be auctioned off on May 16th.
