Make Me Prove It! says the bold text in a chiropractors advertisement that appeared in a Los Angeles newspaper around 1921. The chiropractor, Dr. C.C. Petersen, was one of several downtown Los Angeles area chiropractors placing advertisements in local newspapers.
Similar to the You Need Not Be Sick! advertisement by 1919 chiropractor Joseph H. Coleman, Dr. Petersens ad mentions more than 15 so-called conditions that could be addressed with a chiropractic adjustment.
The text is not the easiest to read but the information on the left says: CC Petersen’s chiropractic adjustments remove the cause of so-called:
- Stomach, Spleen, Liver and Eye Troubles
- High Blood Pressure
- Nervous and Skin Disorders
According to the advertisement Dr. Petersen was in practice seven years when the ad was placed. Phone numbers were different in the 1920s and it looks like the phone number reads Phone 67542.
The office was located in Suite 505 to 509 Homer Laughlin Bldg., 315 South Broadway (downtown Los Angeles). That part of downtown Los Angeles was very popular in the 1920s (and still is today). The Homer Laughlin building was constructed in 1896 and is rumored to be the first fireproof building in Los Angeles. Today the downstairs of the building is the location for the Grand Central Market (the oldest and largest open-air market in the downtown Los Angeles area).
Note the chiropractors adjusting hours include three weekdays working until 8 PM. I don’t know many chiropractors in the United States that today have office hours that late in the evening. Also note there are no hours listed for Saturday or Sunday.
Dr. Petersen lists being a member of three chiropractic organizations; one national, one state, and one local. The three chiropractic associations listed in the advertisement read: Member National Federation Chiropractors, Federated Chiropractors of California, L.A. County Chiropractors Association
Certainly a different type of chiropractic advertisement then you can expect to see today.
