From the October 18, 1986 Pittsburgh Post-Gazette.
One of the biggest doughnut chains in Asia this century, Mister Donut originated in the US and was ubiquitous around Pittsburgh in the 1970s and 1980s. This 1986 Halloween advertisement offers a free pumpkin with the purchase of a dozen donuts and a beverage. Mister Donut survives locally, somewhat, in the form of Donut Connection, which purchased a few of the locations.
