Abstract: A two-sided portable scoreboard for simultaneously displaying a set of two-digit scores both frontally and rearwardly upon a single setting thereof. A pair of disks is sandwiched between a front and rear plate for each set of scores to be displayed. The disks are axially mounted so that a portion of each overlaps a portion of the other, their centers being positioned so that one is slightly more than a radial distance from the other. At least one of the disks has a transparent center section that has a diameter roughly equal to one-half the overall diameter of the disk. A set of scoring symbols are selectively positioned and uniformly spaced around the circumferential portion of both sides of each disk. Windows, or other viewing portions, are placed in both the front and rear plates so as to allow a desired sequence of scoring symbols to be viewed therethrough as the disks are rotated.
