This week, we offer this lovely advertising postcard from the Blue Valley Creamery Company, spotlighting three of the company’s facilities in Sioux City, Iowa; St. Joseph, Mo.; and Chicago.
“Churners of the celebrated Blue Valley Butter” is noted on the front of the card. The Blue Valley Creamery Co. had 21 large butter making plants in the United States and was noted for paying the highest price for cream.
