Lady Gaga's first manager, Bob Leone, is set to sell several of the superstar's items at the US auction GOTTA HAVE IT! Rock & Roll Pop Culture.

"The Poker Face" singer's items are to include a never-released before demo CD dating back to 2002, when she was simply known as Stephanie Germanotta. The CD has a copyright of 2001 handwritten on the disk and "Copyright 2002" typed on the cover insert (pictured left). Also printed is Lady Gaga's legal name.

There is also a performance DVD from the OSIA Showcase in 2006 at The Cutting Room in New York City, and an EP from 2005, released as the Stefani Germanotta Band, titled, "Words".

Gaga's recordings will be sold alongside a spectacular line up of rock & roll / pop culture items that are as legendary as the stars themselves. The items run the gamut from handwritten lyrics by Paul McCartney and Bob Dylan, to the brown suede jacket once worn by Elvis Presley at the "Million Dollar Quartet".

GOTTA HAVE IT! is a leader in rare, authentic sports, historical and music memorabilia. It offers music devotees the chance to bid for priceless pop culture items.

The auction is set to run from October 6 - 15.
