Re: IBM striped logo (8 or 13)created by the late renowned graphic designer, Paul Rand -- "Diego", Feb 7, believes "The horizontal stripes also widen from left to right (or vice versa, can’t remember) to emphasize that."

Mr. Rand designed other enduring logos for clients including Westinghouse, American Broadcasting Company, United Parcel, Cummins Engine Company (and more).
