Can't you just hear the little girl saying that to her momma (or possibly grandma)? This unidentified pair appear an AZO postcard without a message of any kind. There are a few clues here, though, that might help us out with an approximate date and place.
Let's have a look at the reverse of the postcard first:
Notice the studio stamp in the top left corner? It reads, "Electric Studio, 424 E. 5th Street." Did you know that there are many "Electric Studios" across North America in the early 20th century? Yes, indeed. I might have caught a break. though. I found a postcard photo on Ancestry that shows an Electric Studio at 424 E. 5th Street in Dayton, Ohio. That was the only match I could find. A search of the Dayton City Directories between 1910-1920 might help out here, but unfortunately those dates aren't available online.
So, what else does the postcard back tell us? We know that this postcard dates to after 1907 because of the divided back, which allowed a side for the address and one for the correspondence. But there is a way we can narrow that down even further. This postcard was made using Kodak AZO paper, and you will notice four triangles at each corner of the stamp box. That, in combination with the style of font used in "Post Card" and the exact wording of "Correspondence Here," rather than just "Correspondence," narrows down the time frame to March 1910 to 1918.
Can we do better? We can look at the fashions in the image itself. I'm by no means a fashion expert, but if I had to guess, based on the woman's dress and hat, I'd date this around 1912-1915. Her skirt still seems to be ample, not hobbled, and yet not as wide as the princess lines of later years in the decade.
While we don't know who the pair are, we can probably say that the image was taken in Dayton, Ohio sometime around 1910 to 1918.
