Diamond Supply Co. has issued a challenge to all the Photoshop warriors out there in a design contest. The rules are simple, you have until April 15th to submit a design on the template given, however no parodies and original artwork only. The submission must be posted in the Diamond thread on Hypebeast Forums. The winner will receive a pair of size 10.5 deadstock Nike SB Tiffany Dunks. With the going market value, that’s worth north of $500 USD. However, if nothing good is chosen by Diamond Supply Co., no winner will be announced. Refer to Nick Diamond’s post for more details including the template.
