Original oil and gas trade magazine vintage ad for WICKWIRE SPENCER STEEL COMPANY. Survival calls for the right kind of muscle. Powerful, constrictive muscles give the python the crushing strength that enables him to exist under the grim rules of jungle law, where on ly the fittest survive. Same way with wire rope. This unique 1953 old oilfield petroleum industry magazine advertisement would display beautifully matted and framed. Art by Woodi Ishmael.
