Tony Hawk bought the original version of the skateboard, which features the artwork for Iron Maiden’s album ‘The Killers’, at an auction last year. Hand-painted by Cobain back in 1985, Hawk went about tracing the skateboard’s authenticity. Yesterday (February 20), Hawk released a series of the “unicorn” skateboards as well as prints/stickers of the design. Proceeds going toward raising awareness for mental health and for groups building skate parks.
