Circa 1899. “Chicago & North Western Railway station, Elmhurst, Ill.” 8×10 inch dry plate glass negative, Detroit Publishing Company.
This is Rauleigh, previously seen in the colorful kitchen. He’s almost 10 (Edit: I made a mistake, he is about 8 in these 1951 photos) in this Kodachrome taken at the “south porch” door of a cabin in Running Springs, California in 1951. From a set found in a thrift store.
