This is a New Martinsville 1 quart glass pitcher.
The clear pitcher has vertical ribs, and on the bottom is the New Martinsville etched glass mark of N over M in a circle.
The pitcher was made somewhere between 1901 and 1944 when New Martinsville became Viking Glass.
The pitcher measures about 6.25" tall, 7.5" long including the handle and spout and 4.5" in diameter.
It is in good pre-owned condition, but has a hairline crack on the bottom.
