Dating old photographs can be tricky and the above postcard is rather unique. On the reverse it does have a 1919 postmark, which means nothing. This photograph was taken in the spring of 1915. The Knoch Building on left did not add a third story to that structure until the fall of 1914. The Emerson Hotel to left was destroyed by fire in August 1915. Finally, there is a banner across Main Street. It was placed there in the first week of April 1915 promoting Lassen County Day at the Panama Pacific International Exposition in San Francisco.
