Today in 1873, US Patent D6383 S was issued, an invention of John Oesteeling, for his “Design for Beer-Mugs.” There’s no Abstract, but the application describes it, stating that the “design consists in making the upper half of the body of the beer or ale glass barrel shaped, and the lower half of a reduced diameter, with straight or slightly-concave sides, so as to present the appearance of a stem.” Looks more like an ice cream float glass than a beer mug, though.
