I love this cutaway view of Washington DC’s Evening Star Building, drawn in 1922. The building is on the National Register as a Historic Landmark and was formerly the office of The Washington Star newspaper.
Best viewed huge. The whole thing is a fascinating view of how information flowed through a newspaper company in the 1920s. Raw materials in the form of electricity, water, telegraph messages, paper, and employees enter the building and finished newspapers leave out the back.
