Convention and Comic giveaway premiums

Attending Toronto comic cons since the 80's allowed me to amass a nice comic themed pinback collection. These are 12 examples from various vendors at the cons. Free swag use to be the norm, now its doled out with measure or with purchase of the product.
Some neat pins here from comic publishers as DC, DarkHorse and Image. Canadian Horror publisher Rue Morgue and a pin from the second annual Toronto Zombie walk are neat and harder to find.
All of these pins c. 1989-2000's.
