I've tried to get a theme going on certain parts of the rear of the Jacket. Eg. The Big 4 German Thrash bands on the left, a British Metal/Rock theme on the top and the right (and the centre with a Maiden back patch), the Big 4 US thrash bands on the bottom.
Don't really have any theme(s) going on the front though. On the pockets are pins - Immolation and Run DMC (Left) and Guns N Roses, Ramones and Psycroptic (right).
