ATTENTION COLLECTORS: I found this square glass dish in my late mother's house. I don't know how old it is. I think that it might be by Westmoreland Glass Co. of the USA, English hobnail 555 Line. It measures about 6.5 inches in diameter and 1.5 inches high. In great condition, no chips or cracks. Item is in Nipawin, SK; pick up here. Due to current conditions, I accept Interac e-Transfer only, no cash, and pickup will be outdoors.
