Here is a PDF for a reproduction of a 1942 Iodum - Potassium Iodid 10 tube box.
It is made from scans of an original item in my collection.
The original box is made from a medium weight dark brown/grey card stock laminated on one side with a lighter brown paper that forms the outside of the box.
I needs to be printed at 110% scale in order to obtain the correct final size.
There is a discussion on the use of potassium iodide - iodine solutions in the general discussion forum.
I have included photos of the original and reproduction item above.
