This is a cancelled check from the Rough on Rats rat poison originator E.S. Wells, displaying the lurid iconography (dead rat) associated with E.S. Wells, a NJ chemist. A firm believer in advertising, Rough on Rats developed several strains of marketing, including a Rough on Rats theme song. The concepts were quite modern (except for some blatant racist depictions) - so modern they can almost be called a "rat-poison lifestyle." SOLD for $5.
