Old Buchanan Black & White
It is highly unlikely that it is from the 1890s as Queen Victoria was the monarch at the time, not a king. Victoria reigned from 20 June 1837 to 22 January 1901; after which her son Edward VII inherited the throne. The original Black and White did not display the Scottie and West Highland Terriers on the label. The terriers came later. The original bottle got its name as Black and White because the bottle was black and the label was white. People readily recognized it because of these two distinctions. A picture and any numbers on the bottle would have to be supplied to determine the age. But it is definitely not from the 1890s. It would have to be after 1901 at the earliest as Buchanan wasn't born until 1849 and there was no king from 1837 through 1901.
