must-have ! Vintage 12" Ruler Lot of 36 Wood Plastic Metal Advertisement Unions NFL Coke

This is a mixed lot of 36 student desktop 12" rulers. They are a mix of plastic, wood, and metal and are from the 1960s to early 2000s. Some are standard student rulers but remarkably are advertisements of some kind with a list of some of the companies listed below. If you need specifics, please let me know. There are only a couple duplicates. Some have names written in black marker as these are from a teacher and were left by students over the years. At the time of this listing, I have a lot of smaller 6" and other types of rulers up as well if you are interested.
