The proportions in this piece are nice. However, the left side is a lot heavier than the right so to me it throws the composition off. It would be better it the piece would have been balanced better.
Again color is very minimal. However the color seems to unify the whole piece which makes it come together nicely.
"Kassama Corn Flour" (1900)
This poster is very simple. There is minimal color and also there is a nice balance between the forground and background.
All of these pieces have one this in common, they all are minimalistic in color. There is barely any color used but what color is used seems to go along with the advertisement of the individual posters. For example, the "Rowntree's Elect Cocoa" is overall brown in color but cocoa is brown so color goes along with the advertisement. All of these pieces are basic as well. There isn't a lot going on but simple is sometimes best.
