Heroes World had retail stores popping up all over the country and had practically become a household name in comics by 1980. They were consistently one of the most active advertisers in the pages of Marvel comics during the late 70s and early 80s, so their ads make for a great journey back in time to what comics, games, toys, etc. were available during this era. In this case, Mego's Superhero Dolls, a Spider-Man ski mask, Hot Wheels for Spider-Man, Hulk, Captain America, Thor, the Human Torch and the Thing. Great stuff!
