This real photo postcard of the AZO brand shows three children somehow connected with the Rudd collection. Unfortunately, no one took the time to write on the back of the photo identifying who they are. The stamp box has the triangles pointing up on top and down on bottom, so that dates the card between 1910-1930. I’d guess this is somewhere in the middle of that range. I love how the socks are all a bit saggy, which to me indicates these are normal, rough and tumble kids who dressed up for this particular occasion.
