The images you see here are mostly from 1905-1925. There might be a couple outliers. Click through to see the context, or to see a larger copy of the picture at Google Books.
Many of these are from advertisements, which seem to be the easiest place to find views of kitchens. People didn't seem to show off their kitchens much then, so they aren't usually pictured in pieces about new houses and such. But they are in lots of ads! There are also some images of "model kitchens" from plan books and magazines.
More to be added soon!
