We had a bunch donated to CHAA by a lady who collected them during the war.
They were collected mostly by kids (kinda like baseball cards) and were sold for 10¢ apiece, as you've noted.
However, they weren't all RCAF aircraft. These were generic photos of aircraft released by the censors for public use.
For example, Hurricane K5083 that you have shown is the prototype aircraft.
Hope this helps.
