LUDEN'S MENTHOL COUGH DROPS
1924

Series of 1919 1¢ Proprietary in 1924 usage on a Luden's Cough Drop box.

Considered medicinal at that time, yet selling for only 5¢, the box provides many of the reassurances patent medicines traditionally did, and promises that the product is never touched by hand.

The other side features a picture of a huge factory, further enhancing the product's image as a modern, safe medicine.
