1945 US Bubble BOOM
In 1945 there was a bubble BOOM across America. Seeing a good thing, many chemical manufacturers jumped on board with their own mixes... often calling them Rainbow Bubbles.
This manufacturer might have thought things through a little better in their advertising. For sure, the company's main products were insecticides...
I do wonder how well these Rainbow Bubbles from KILLS 'EM CHEMICAL CO sold. And @ seven dollars fifty cents per gallon? That was expensive.
