If you've already registered at FITC then you no doubt have your mini metal wrestler figurine that was in your registration bag.
The folks at Happy Worker have posted a how to guide that will help you paint your wrestlers. Give it a shot to give them some colour. If you want to see samples swing by the registration desk - there's a three piece set there that's completely painted.
