Longtime readers will remember that the Graphic Arts Collection contains a candy wrapper collection established by Ephraim di Kahble, a fictitious member of the class of 1939. https://blogs.princeton.edu/graphicarts/2008/11/graphic_candy.html
Kahble was invented by Frederick E. Fox, Class of 1939 (1917-1981), who wrote to American candy companies as a Princeton freshman and gathered a collection of wrappers, fliers, and stationery.

We thought we had all the candy recorded but recently, graphic material from the Hershey Company appeared, including this enormous broadside describing the location and history of the company’s factories.

To request the collection, please ask for GC149: Printed Ephemera, Candy
