Sure Death Poison Fly Paper from the 1920s, crafted by the Pfeiffer Chemical Company of St. Louis, MO. 
 
This vintage framed envelope is not only a unique piece of pest control history but also a striking conversation starter for any home or oddities cabinet. It features vibrant, blood-red ink and fantastic graphics including the infamous poison skull and bones symbol. Infused with a potent arsenic formula, this fly paper was once the go-to solution for households seeking to eliminate pesky flies (or cheating spouses) quickly and effectively.
 
Please note that this item is intended for display purposes only. Handle with care and keep out of reach of children and pets. The envelopes are old and long empty, however, I do not recommend handling this envelope outside of the frame without using gloves or other safety precautions!
