I was interested to see a mention of Victor Gorden Tupper on the internet, and more specificaly on this forum.
I too have a copy of the very same book, and began reading it tonight. Very interesting account of the great war and Gordies experiences. I assume your Aunt Grace or "giggy" is the "geegee" mentioned in the book?
I believe it was given to my great-grand parents (the Johnsons of Vancouver) who were good friends to the Tupper family. In fact Sir Charles and his wife were/are god parents to my aunt.
