Topps worked hard this year to get as many GPK products on the market as they can to help celebrate the 30th anniversary. The last of these officially licensed products are Halloween masks made by Trick or Treat Studios. The company is offering 4 masks and 1 decoration in their GPK line. Ranging in price from $60-$80 these masks will allow you to be the only kid on your block dressed as a Garbage Pail Kid! They are offering Ali Gator, Bony Tony, Creepy Carol, and Zeke Freak as masks, and a Glowing Amber decoration for $50. Check out the links below to get your GPK on for Halloween this year!
