1974 3M Microfragrance Scratch and Sniff Library Kits
In 1974, 3M produced a kit called "Microfragrance Scratch and Sniff Library Kits". It's purpose: learning through the sense of smell. A sticker is placed on the top of a "Fact" sheet with
information about a particular smell. (See Candy Cane Sheet below)
These Kits were Most likely distributed for free to a bunch of local schools in MINNESOTA. (Near 3M's Factory) The pamphlet in the set tells of 2 more sets
that could be ordered. None of these sets have been discovered though. Do they exist??
