A little history......
Valentine & Sons Publishing Co. (1907-1923)
Montreal, QC and Toronto, ON, Canada
The Canadian office for Valentine’s of Dundee, Scotland. They published souvenir books, greeting cards and view-cards of Canadian scenery. These tinted halftone and collotype cards were printed in Great Britain. Valentine sold their Canadian branch in 1923.
I bought this card, and a few others, in about 1970 from a young man who was selling the contents of his grandmother's house. He had inherited her home that at that time was about 120 years old and it was full to the rafters with family memorabilia that he didn't want. I bet he's kicking himself in the butt now. Imagine, selling all that stuff away to strangers.
p.s. I just noticed one of the cards I bought is from 1876 :)
