Early 20th century Souvenir book
The Grandeurs of Niagara
Niagara Falls in Summer and Winter
by Pen and Picture
Impressions by Great Authors

Each page is a black and white photograph and text of an image of the falls or some structure (bridge, electrical building) surrounding the falls.  

There is no date in the publication, but there is a reference to the electrical production in 1905 so it's likely printed in 1906-1910 where that year would have still had some meaning.

See photos for detailed condition (this is the item you will receive).  All pages present and tightly attached.  Some discoloration to edges of cover.  No tears
