Amazing vintage find! New old stock case of Red Cross menthol cough drops.

Full, early cardboard box is made to be folded into a retail display. In the display box are 20 new individual boxes of cough drops sealed in wax paper and priced at 5¢. Most of the small boxes are perfect, but some do show signs of being handled. I photographed 3 that had issues with the wax paper.

I haven't found an exact date, but I believe these are from the 1930s.
