I'll bet that is tied to the Pure Oil Company. After looking up a few more things. I was able to narrow down the date to late September, 1921 when the Pure Oil Company purchased the PO Company of Minneapolis. I found ads prior to September 21st stating that they are "emphatically independent". I then found the same ads in early October, 1921, with the Pure Oil Company logos. Unfortunately, I couldn't find any stories regarding the actual purchase. Hopefully i'll be able to find something eventually.
