Ozzy Osbourne recently teamed up with Dogtown Skates to launch the Ozzy x Dogtown skateboard and clothing line to celebrate the 40th anniversary of the release of Metal Legend’s "Madman’s Diary" album. Now fans have a chance to win a limited edition Ozzy skateboard deck signed by Osbourne and deck designer Dogtown puppet Jim "Red Dog" Muir.

The deck-a shining masterpiece of the Ozzy x Dogtown series, featuring the art of Sean Clive-is one of only 200 custom-painted "midnight fade" panels with a silver sheet metal finish. Manufactured by Paul Schmitt of PS Stix, Screaming Squeegees's Chicken handmade silkscreen, they adopt the classic Dogtown "Stonefish" shape of the 1980s.

Check the deck and participate in the following competition.

The 10.125 inch x 30.325 inch skateboard deck that was first released at the end of last month has been sold out in Dogtown's online store, even without the signatures of Osbourne and Muir. Another retail version of the deck dyed in various other colors has also been sold out. Ozzy x Dogtown clothing items such as shirts and hoodies are still available, but they are growing rapidly.

Osbourne's Diary of a Madman, Black Sabbath idol’s second solo album, was originally released on November 7, 1981. This year, the updated digital release of the album's 40th anniversary includes a new track, the live version of "Flying High" again. "
