These views were drawn for inclusion in the Bristol Observer - a weekly Newspaper.
The sketches date from around 1906. Each week the front page of the Bristol Observer displayed several views of local and distant towns and cities. Sometimes a suburb of Bristol, sometimes as far away as Japan. Bristol Reference Library has bound copies of the paper dating from 1859 to 1962.
The artist Samuel Loxton drew literally thousands of illustrations for Bristol newspapers. You can read about him by following this link. The architectural details are accurate and sketches like these duplicated more clearly than photographic images with the printing process in use then.
