This 1943 advertisement for Bag Balm (still sold today as a top product for chapped hands and other parts) captures a moment in the product’s history when, it seems, competitors had come into the market with similar-seeming products. The ad walks a fine line between extolling the virtue of its class of products (selling farmers on the idea of using balm at all) and reminding potential customers that, should they decide to use a balm, they should use this one.
