Burger King Trick or Treat Bag, 1977

The recommended "Halloween Do's and Don'ts" on the back of this bag convey the nature of trick-or-treating in the late 20th century. Some advice addressed trust and personal safety (don't eat treats "before Mom or Dad say it's okay" and look both ways when crossing the street). Other recommendations included etiquette and proper behavior (don't litter or damage anyone's property).
