Believe it or not, Italian Fisherman is a popular name for a restaurant! There was one in Port Orange, FL which was a favorite of mine but there were many more places over the years and I haven't tracked this one down.
This glass stands 5 1/2 inches tall with a very cool turquoise pyro image of a chef tasting from a spoon and with baskets filled with fish and produce at his feet. Italian Fisherman is across the image.
No maker's mark. Perfect condition.
