My dad passed away this spring and I found in his things a miniature bottle (but maybe 4X bigger than the airplane size) of Johnnie Walker Red. It is still in its original cardboard box. I don't see a volume written on the label anywhere. My dad was not a drinker at all, but he tended to get given things and he would put them on a shelf and they would stay there until I found them. Also found some champagne that was more than 20 years old (and probably undrinkable). This thing might be pretty old. It has never been opened. It has a metal screw lid, not something that looks super antique. But I have never seen a bottle this size or a miniature that comes in a box. I almost opened it tonight to drink it, but thought maybe I should find out if it is worth anything. Probably not, but trying to find out. Anyplace particular to check? Anyone here able to help?
