Circa: 1926 - 1944
Manufacturer: New Martinsville Glass Co.
New Martinsville began production of the #4500 line, Janice in 1926. Viking continued production beginning in 1944 but I'm not sure how long the blue color was made. These elegant tumblers are in vibrant light blue. Each tumbler measures 4 7/8" high and 3" wide at the mouth. All are free of any chips, cracks or discolorations.
