The tag-line of this blog is “A tiny window into 637 Periodical Titles & 200,000+ images divided into 910 Picture Subjects.” 95 of those subjects have the parent subject Advertising. There are 16 subcategories of Advertising (Beer, Cigarettes, Cosmetics & Grooming, Drugs & Medicine, Fashion, Finance, etc.). Those subcategories are then divided chronologically, for the most part into decades. This arrangement allows users to see how illustration (or the lack of it), graphic design, copy, and advertising strategies have evolved over time.
Advertising–Tourism, which has nearly 1000 items, is divided thus: 1890-1919, 1920-1929, 1930-1939, 1940-1949, 1950-1959, 1960-1969, 1970-1979, 1980-1989, 1990-1999, 2000-2009, and soon 2010-2019. A generous sampling follows.
