Alexander Wang has created a crowd-sketched bag with Samsung

The fashion designer asked members of the public to come up with a cool new gym sack by drawing their own doodles on Samsung's Galaxy Note II smartphone for him to merge into one funky design for a lambskin bag, which will be sold for $550 and donated solely to Art Start charity.

Art Start is a New York-based charity that uses artists aged between five and 21 to create masterpieces in a bid to help less fortunate communities and encourage youngsters to embark on successful creative careers.

The black and grey printed bag is Wang's second collaboration with Samsung after he created a limited-edition print that was used on a bag and mobile phone cover earlier this year.
