Be warned should you choose to go clowning around this Halloween. Within the steady stream of trick or treaters lining the amber-lit streets to collect their sweets there walks a demonic presence, searching for its next victim. The leaves fall, tumbling to the ground below just like the droplets of blood from a sharpened blade. Trick or Treat? Pray it's the latter, or your blood's gonna splatter! Spiral Trick Or Treat T-Shirt Black is made of Top Quality 100% Cotton, Jersey using skin friendly, Azo-free, Reactive dyes.
