This blank postcard, labeled "Efficient Citizenship No. 454," promotes the achievements of the New York Milk Committee and allied agencies in their fight against infant mortality from July 1 -15, 1911. Statistics from thirteen American cities are provided, as is the reason for the campaign's success: access to, and use of, "good milk." The postcard verso includes a chart of "baby deaths for one year" -- tracking seasonal changes in mortality rates -- and asks the reader to consider, "When does the spurt come in your city?" Contact information for the New York Milk Committee is also provided.
