likely dating between 1944 and the 1960s. The clear glass
bottle is embossed "Lamb Mason" across the front and "13A"
on the lower base. The bottom is embossed with the letter
"L" above an empty circle. Date estimates were ascertained
from the markings. The Lamb Glass Company of Mt
Vernon, OH, operated between 1921 and 1963. It is in great shape, free from breaks or cracks.
Embossing is sharp. The old jar measures
about 9.25" x 4.5" x 4.5"
