Steven Noble has created an extensive collection of logo indentities that covers almost two decades worth (1991 -2012) from large size multinational companies to small start-ups. The mediums and styles used vary from bold woodcuts to fine engravings and line art.

This rule means that the average person glances or looks at a visual logo for up to 3-5 seconds and therefore the message needs to translate quickly. If they can't understand or translate what's going on within that short timeframe then you know right away that it doesn't work well as a logo identity in the long run.
