PROGRESS insetticida 1950'
A curiosity. The container can be screwed on a bicycle pump.
On the container face, you can read this (about insects and paest) : Their last hour has come.
Insektsspruta - Bug spray history and brand directory
You'll find on this page a part of my interest in these old bug spray made all around the world from 1919 to 1974. They were used to kill pest and insects.
Don't hesitate to ask me for questions, if you are looking for french brand to complete your collection, I'm also looking for Swedish items.
Thanks for reading and have a good day
