for sure a liquor bottle of some sort , the star may imply some type of jewish connection ? if there is any liquor or wine made or used by jewish people .
I've seen liquor bottles that were almost identical may times before but not the star on bottom
At first I thought maybe Seagram's Five-Star whiskey? Maybe not, since Canadian distilleries have traditionally used flasks for bottle quantities less than 26 ounces, other than labelled and clear 2 to 4 ounce rounds. Highly unlikely to be a beer, as by the age of this bottle, Canadian brewers were using ABM crowns.
