Most of the photos on this site were extracted from reference images (high-resolution tiffs, 20 to 200 megabytes in size) from the Library of Congress research archive. (To query the database click here.) Many were digitized by LOC contractors using a Sinar studio back. They are adjusted by your webmaster for contrast and color in Photoshop before being downsized and turned into the jpegs you see here.
The photographer was facing east, looking down Edmonson Avenue from the point where it crosses Rolling Road. The convertible (double-ended) Baltimore Traction Company trolley has departed Catonsville Junction and is headed west on the No. 9 Line, a jerkwater route terminating in Ellicott City. This line was abandoned in 1955. Judging by the cars in this image, this photo dates from right about that time. View full size.
