Untitled advertising image by Philip R. Goodwin
From wikipedia, Keen Kutter is a trade name first used by Simmons Hardware Company of St. Louis, Missouri in 1866. The name was adopted as a trademark by Simmons Hardware Company in 1870 and was used on their highest quality tools and cutlery.
I have five or six pieces of Simmons Keen Kutter billhead such as this one, and I like using the itemized list as a foil for the art I put on it. I am a big fan of the advertising artists of the late 1800s and into the turn of the Century.
This is just one example of the use of a certain brand (UMC/Remington), only for the image to be sold to another brand (Peters) and the product was replaced by Goodwin.
