I happened to find what is considered to be one of the rarest Arm And Hammer Baking Soda commercials from the 70's. The commercial is animated and features a talking baking soda box trying to settle an quarrel between food in a fridge and when I first saw it the animation reminded me of Spongebob Squarepants. In 1989 Arm And Hammer did a remake of this commercial but with clay animation and it shows how impressive commercials were in the 70's
