The Church and Dwight Co.was formed in 1847. It is commonly recognized by its Arm and Hammer trademark, which is modeled after Vulcan, the mythological god of fire and metalworking. The company issued its first bird cards 100 years ago in an effort to raise public awareness of threatened wildlife. Baking soda birdcards, especially those illustrated by Louis Agassiz Fuertes, are highly collectible today.
