[AMERICANA - 19th CENTURY EPHEMERA] AMERICAN COW MILKER MACHINE POSTER, ORIGINAL. Buffalo, NY: Express Printing Company for the American Cow Milking Machine Co. [n.d. ca. 1865]. 42 x 26 3/4 inches. Woodblock printing: Boldest typeface measures 10 inches tall. L. O. Colvin's "American Cow Milker" was patented in 1860 as the first use of teat cups with a vacuum. The milker was used in England, but the constant vacuum pressure caused problems with the cows' teats. He sold the patent in England for about $5,000, after selling over 1,500 machines. He continued to make improvements and was more successful in America where this undated broadside was published. "Triumphant Success | The Most Important and Valuable Invention of the 19th Century" proclaims the headline; the company is seeking business men to invest/sell the machines; the farmer is being courted. "A sure cure for aching hands & kicking cows." Several archival tape repairs to reverse with no loss of text. Heavy newsprint stock, printed in black. A few small closed tears to edges, and some light foxing. Very good overall. We have located a smaller version of this advertisement, but none this size.
