Here is another version of the 136.4 Canadian Boston in terms of color. This one is from my collection and is a heavy chunk of glass in a light sky blue. Exceptional wire rim with only one chip. Has the dome dot and mold line over the dome. Nice milk swirling in the dome along with micro-bubbles. has a small crack radiating from a "V' shaped chip at the base. $195.00 shipped to your door.
