The "fat" CD 102 is in the center, it has unusually thick glass, as evident in this view. Smooth base, but with some smal ripples that look similar to "feathers" when viewed close-up wuth an eye loupe. Color is aqua, and the glass is very clear, with just a few bubbles. There is a small backwards 2 on the dome. The base measures 2 1/2 inches diameter, the other two measure 2 1/4 inches diameter. This middle guy oughta hit the gym and stay away from Krispy Kreme ;-)
