A good modern trademark interprets the character of its wearer by associating it with sharply defined patterns of visual forces. The well-known emblem of the Chase Manhattan Bank designed by Chermayeff and Geismar may serve as an example. The inner square and the outer octagon produce a centrically symmetrical figure, conveying the sense of repose, compactness, solidity. Closed like a fortress against interference and untouched by the changes and vicissitudes of time, the little monument is built of sturdy blocks defined by parallel straight edges and simple angles.
