Curious bottle you have there...I have a 1/8 Pint version of this!
Black&White was a pretty common 'shelf-brand' whisky for many years,
but not too highly regarded for taste these days...Still there are a few
indviduals that would collect these simply for their age. (Your bottle
dates to the 1960's I believe.)
If you ever think about ******* it, I have a pretty big collection of these
Black&White bottles going back to about 1917...would love to add this
one to the collection!
