77. “CONGRESS SPRING CO. S.S. N.Y.” (on the base), (C-22 variant), New York, ca. 1870 – 1880, blue green, 8 3/8”h, smooth base, sheared and tooled lip was been expanded out to create a drinking vessel, perfect condition and with crude whittled glass. An extremely rare end-of-day glass blowers whimsy that fits so perfectly in the hand one could easily imagine an 1870’s glass blower at home drinking a porter from it. Early glass blowers whimsies are very rare and this one is exceptional!
