Looking at the photos, I see Canadian and other Commonwealth or Territorial regiments represented... They all seem to be regiments that saw action in WW1. I would imagine these were a sort of recruiting tool from that time, but I can't find any like them online.
My thought is to contact either the Imperial War Museum, or the National Army Museum in London and send photos to them, I would think that if these existed anywhere else one of those two collections is likely to have them or know of them.
Good luck and I hope you'll update us if you find any info elsewhere
