The reason for the locations of Glasgow & Bombay relate directly to the days of British colonial rule, with the third Toronto due to the large Scottish population in Canada at that time.
Blackie & Son appeared to publish nearly every one of my school books, in those far off days when I went to school, they were a sort of Scottish institution, and a source of great pride to many Scots, and particularly to Glaswegians like myself.
