From the Harvey's Hotel and Casino Postcard Collection (PH-00367) -- Interior view of the Bucket of Blood Saloon in Virginia City, Nevada. Inscription with the image says, "The interior of the Bucket of Blood Saloon is in stark contrast to the sinister name it bears. Like so many of Virginia City's famous landmarks, it was rebuilt in 1876 after being destroyed by fire. In a mixture of the old and new, it has many lovely hanging lamps and mirrors of the early era. A portrait of Sandy and Eilley Bowers, that they brought back from their tour of Europe, is proudly displayed with other mementos of the past."
