I found this image in the 1983 periodical of Graphis. It was made by Stephan Geissbuhler. The hierarchy of this piece is the phrase, "Taking things apart and putting things together what chemistry is what chemists do and what the results have been." It was a poster made for a chemist exhibition for the American Chemical Society for their 100th anniversary. The letters in the text are element symbols and the typography also symbolizes the idea of taking apart and putting back together. Although the picture is shown in black and white, the text says that the poster was originally white green and blue. I think this those colors the piece would look stronger and more appealing. The piece is very clean and to the point. The use of line and spacing are emphasized through out this piece. Vertical and diagonal lines are used.
