Unknown locations

AZO Canadian back, unused, no place given. It isn't clear whether the house is on fire or whether it is being sprayed with water to prevent it from catching fire.

Location unknown. Unused. One of the later AZO cards, likely c. 1915-20. I tried to read the little handbill or sign that the man in the light-coloured coat, third from right, is clutching, but I can't make it out. Looks like it might be showing part of the word "competed". Other people have ribbons so it seems to be some sort of competition day. But where??? Are these guys returned war vets?

A dealer has written "Ninette, Man." on the back. It's possible but hard to say.
