I love this photo, which I found on American Social History Online.
I was searching for images of suburbs, homes, and families, between 1945 and 1970. It captures the sentiment of the moment, evoking the nuclear family of that age. I learned much more about American Social History Online while participating in THATCamp at the Center for History and New Media.
It comes from the Charles W. Cushman Photograph Collection at the University of Indiana Archives: http://webapp1.dlib.indiana.edu/cushman/results/detail.do?pnum=P10954
