*from "Advertising Agencies" section. Direct mail and specialty agencies in this section were omitted whenever their names suggest, as well as "Advertising Service" and "Advertising Specialty Business" sections. Since "general" agencies and occasional specialty and direct mail agencies are not identified by their names, these figures are probably not pure strain.

**Several specialized agencies are also listed at this address. In addition several addresses which are blurred on the photostats appear to be "67 W. 44th Street." These addresses were not counted.
