picture of Boy and dog going to a dog show

I just saw this for the first time and was wondering if anyone can add to what I know. This picture was sent out to a teacher in Buffalo Hump School District 3809, in Norquay, SK It was mailed on May 2nd 1956, I believe I met that teacher in the late 199s, I moved to Norquay in 2003 and got to know her, sad to say it was her passing away and her family cleaning out the house and passing some of her belongings to one of my sisters that had helped her with a lot of quilting, I had not seen very much of the papers and such as they were stored away. My sister was looking for a quilting pattern that had her bring these items to my attention, I also have pictures of a poster that I will be posting also it is dated 1940 right on the front of it it has been cut in 2 pieces and was in behind a picture and when we were trying to find out what we could on it this was in behind the picture
