I forgot I had this promotional comic from 1976 showcasing all the superhero merchandise that the comics of the time advertised. There are great ads in here that brought such great products as t-shirts, toys, calendars, records, and even that staple of 70's bedrooms, black light posters.
That Cap poster is fantastic. There are way too many cool stuff in this book to post here but I thought I'd show part of the cool selection of cool Marvel shirts that were available at the time. 1976 was a great time to be a superhero fan!
