"Many a small thing has been made large by the right kind of advertising."
- Mark Twain
From the turn of the century through World War I, advertisements in Trinity School's publications were primarily from local businesses including grocery stores, food markets, coffee companies, dance instructors and dentists which were patronized by students and their families. Many of these businesses also had a direct relationship with Trinity School including Gulden’s Mustard, a New York institution. Another example was A.G. Spalding & Bros., the sporting goods manufacturer which ran ads in Acta Diurna and also made sweatshirts for Trinity's athletic teams.
