#2: An Iconic Photograph
While this photo may not bear any particularly large historical significance, it does have a particular historical value for those familiar with the works of renowned photographer Walter Chandoha. In 1955, he shot this photo of his daughter and a small kitten perched on her shoulder, which became one of his most famous works.
Aside from the extraordinary fact that he managed to have both his daughter and the cat smile at the same time for long enough to take the photograph, there is also the remarkable coincidence that both subjects have the same gap in place of their front teeth, making for a very cute and memorable shot.
