1974 McDonald's Grimace Tin Foldover Pin Tab Back Button

Tab back buttons shown in Joyce Losonsky's Pre Happy Meal Book as being from 1974. Not dated. In plastic. Has a staple on each one to keep them from falling out. Ronald has a little light wear to the white area, Grimace has a couple of scratches, one through his right hand and the other on his left lower area, Mayor looks great with just a couple tiny specks of white missing and Big Mac has a few specks of white missing. Backs look great. Hard to find items. Never bent back. Looks like from a place in Chicago Ill.
