This one should have been easy, but it has me stumped. Perhaps someone here can help. The bottle is embossed with Liberty Brand Cold Packing Company Oakland CA. on three of the ten sides. It is 2 1/2" in diameter. The seam runs up to the shoulder and then stops. There is another seam, offset by 1/8" that runs through the top. Some air bubbles in the glass. A small 7 is at the bottom of one of the sides, and the letters P and C in trapezoids at the bottom of another. The trapezoids are separated but positioned so that they make a rectangle.
