I found this great One-Spot Flea Killer packaging at a junk store down a country road on the Old Mission Peninsula near Traverse City, Michigan.
The silhouette on the bottle is the same as a giant 2-story cutout dog that flanked either side of the One-Spot Co. factory on Washington Blvd., in Elkridge Maryland in the mid-1940’s. I’ve heard that the enormous dog was visible far down the road, with neon lights illuminating the words “One-Spot Flea Killer”. Stories tell that a drive past the factory was considered a “reward” by the local kids.
