I believe these are scarce. This is an Argentinian carnival glass tumbler in BLUE glass!
The shape of the tumbler is really neat and the coloring is prettier than most Argentinian glass, I’m told.
Note one nick to the rim edge as shown. Please ignore dark areas. I’m not good with this indoor lighting sometimes.
Made in the early 1900s.
3 5/8 inches tall
2 1/2 inches top diameter
1 13/16 base diameter
