Matthew Barney has teamed up with Juxtapoz Magazine to produce a new Drawing Restraint 19 skateboard. The board features a graphite nose, so the rider creates a drawing as s/he skates.
Juxtapoz recruited skateboarding legend Lance Mountain to be the first (and, so far, only) one to ride the board at Ride It Sculpture Park in Detroit as part of a series of artistic interventions in the neighborhood.
A special limited run of 1,000 copies of the February issue of Juxtapoz have been published with a special Barney/Mountain cover. Juxtapoz also created a video documenting Mountain's time in Detroit.
