The money is being raised as part of Planet Rock's Movember campaign, which raises funds and awareness for men's health issues, specifically cancers that affect men.
The Pure Evoke-1S Marshall digital radios have been signed by members of bands such as Foo Fighters, Thin Lizzy, Def Leppard, Status Quo and Deep Purple. Alice Cooper's autographed radio is pictured above.
