This is a boxed set of chocolate bars commemorating the original legendary writers Blade, Crash, Crachee, Crime79, Dondi, Revolt, Iz The Wiz, Lady Pink, SparOne and Stay High 149.
I originally bought it about 4 years ago, sadly second-hand which meant I never had the pleasure of tasting the undoubtably fine chocolate and instead only had the wrappers.
From what little information I can gather about them, the artists were paid to use their images and the profits went to charity.
Whatever your morals about this; corporates using any latest bandwagon to sell their goods, or just a nice idea to give some props and recognition to deserving artists, they do look damn good.
The makers are http://www.chocolatebarnyc.com although not much more info is there. However this short video shows a little bit more, including the chocolate itself, well almost.
