Mastodon got signed, Pt. 3

My wife's most unique Mastodon item that I keep safe in my collection is the signed booklet of her Leviathan CD. She got this signed at the band's signing at Download Festival 2007.  She got this from the same Mastodon signing at Fopp in London as my 'The Wolf Is Loose' 12" picture disc. The signing was part of their tour with Tool. Their London show was held at the Wembley Arena.
