Reward Revealed: Pipe Organ Brass Knuckles
Of course these are for decorative purposes only... unless someone confuses dorian and lydian modes in your presence. Then, you may need them to settle an argument.
If you pledge $500 to the Anywhere Organ project these fine brass knuckle dusters will be yours. They're perfect for wearing out on the town, adjusting your powdered wig, and posing for your own bust.
