Champion Spark Plug

Many of my relatives (Great Grandmother, Grandparents, Uncle) worked at Champion Spark Plug at one point. I recently acquired an upopened box of spark plugs probably from the 1940s. I like the fact it has an inpection packing slip that may have been approved by one of my relatives! I also found some old "Spirit of a Champion" magazine that my Great Grandmother gave me in 1985. It was their employee magazine.
