Found among some old documents. Apparently a poultry business in Blooming Prairie, MN. The man is showing off a Dalton adding machine, which they had probably just purchased. Dalton merged with some other companies later in 1927 to form Remington-Rand, making this one of the last Daltons to come off the line. The 1926 price of a Dalton adding machine was $100, the equivalent of a few thousand dollars back then. They must have liked calendars; there are eight on the walls. Scan from 5x7 contact print.
