This set of two graphs (pie charts and surface graph lines) shows the distribution and growth of Millington's investments in "indoor" (printed) and outdoor advertising (in $). The pie charts reveal a quite equal distribution between both types of advertising media. Though indoor advertising slighly dominated over outdoor advertising in 1929 (53%, almost 62000 $), outdoor advertising tended to take the advantage in 1930, both in ratio and amounts of money invested (52%, more than 100 000 $).
