This is an original, extremely rare 19.5\" x 27.5\" agricultural / farming advertising sign, made in the 1950s or 1960s from embossed metal, promoting a product called Cooper-Tox by the Chicago company William Cooper and Nephews. Cooper-Tox was a livestock dip and spray that contained the long since banned substance Toxaphene, used to \"cure sheep scab\" and eliminate fleas, ticks, mites, etc.
The off-white sign featured embossed red lettering and embossed images of a cow and sheep (modern reproductions of this sign are not embossed and sometimes not even metal). There is very minor discoloration from age, and there are two small bends in the edges of the sign, one in the top right corner and one near the bottom left. These might be fixable with pliers. Overall, the sign is in excellent condition.
I could only find one another example of this sign appearing online. One that was the same size and in a similar condition was sold in a Wisconsin sale in 2025 for $3500. That is the basis for the pricing of this example.
