I try and document all containers containing crayons. Sometimes those aren't so obvious as just an ordinary box of crayons. For example, Art Sets frequently had crayon in them. So did pencil boxes which were also called pencil cases, student cases or school cases among other names.
The cases almost always had a button fastener for the top. They may have contained one to three different storage levels. Nearly all of them included crayons as each of these companies made both crayon and pencil products.
I have a running compilation of all of them here: http://www.crayoncollecting.com/Article-PencilBoxes.htm
These cases run from the 1920s into the 1950s. After that they seemed to have switched to regular boxes or flimsier vinyl cases and other ways of packaging school supplies. I focused just on those vintage ones.
