This William Rott catalogue usefully connects some distinctive features of mid-century sets to this maker. First, the point design featuring points topped with small dits or triangles augmented by an additional dot floating above seems to be a reliable hallmark of a Rott set. Also notable is the tray design placing the dice in the corners of the board rather than the middle, is a throwback to the original Popper patent style, abandoned by AP Games by the late 1930's.
