Dewar's blended scotch whisky
I have a bottle of White Label Dewar's Blended Scotch Whisky, believed to be from the late 1960's. It is unopened as the label covering the top in unbroken. The label number is 576363365 and the other side of the label says NY-I-68. It was kept in a nice dark closet, 86.8 proof. Any ideass?
