Hey Glen
These postcards are hard to locate..The only thing I got is the actual photo that the Legislative building was used in your post card...
The kicking horse canyon in Yoho was hard to find..Did not get your post card, but the only other one was the one below I found..


Try this web sit Glen
https://torontopostcardclub.com/cat...ard-history/ Take a look at this Glen..Wonder if certain printing companies bought bulk load of blank post cards from
Canada Post and sold customers their personal post card with their personal pictures.

Even the states had personal/advertising pre stamps cards
SOME COMPANIES THRIVED ON PICTORIAL POST CARDS TO SEE TO THE PUBLIC


Here are more pre stamped Canadian postal cards that could be used by private printing companies.


Bottom line Glen...If these were part of the Canadian personalized postcards that existed back then..They could have been personal photos printed and we will NEVER be able to track them down.
