Original screenprinted Warlock You Hurt My Soul backpatch from 1985. Like the small embroidered one its also unused and just hase a little crease from storage.
Those backpatches were printed by siraprint. Most likely not too many of the backpatches were printed. Not many of those are seen these days and probably many did not survive due to its fragile character.
Check out my mate DthOnMnSt to see the backpatch with the classic witch :-)
