This "fishbon-style" tree aims to trace and compare the advertisement series for the medicine brand "Scott's Emulsion" in both the Shenbao and North China Daily News during 8 days (from Jan 7 to Jan 15). The series in the Shenbao is traced at the top: one can note that the brand appears only two times a week and offers a different variant each time; the series in the North China Daily News at the bottom reveals that the brand appears every day and offers a different variant each day.
