I apologise if the below details have already been posted on the forum, or if indeed the publication is of common knowledge, but I came across this interesting booklet that was published in 1916:
Photographic record and souvenir of the Canadian Grenadier Guards Overseas Battalion "Eighty Seventh"
It can be found online at:
