English: Many promotional photographs of Louise Brooks from the mid to late 1920s are marked with the "P703" prefix, followed by a suffix of up to three digits. Since Brooks was under contract with Paramount Pictures from 1925 to 1928, it is reasonable to conclude that the studio used this "P703" classification system to catalog her promotional images during this period. Several of these "P703"-designated photos are attributed to Eugene Richee, a prominent Paramount photographer. In the absence of other specific credits, it is likely that Richee was responsible for shooting many of these images.
