Scientific American, Vol. 80, No. 24 (1899)
Scientific American, volume 80, number 24, from 1899, was a weekly American magazine of science and invention for a general readership of engineers, inventors and mechanically minded readers. The pictures are black-and-white halftone and line engravings: a laboratory apparatus photograph with a man in a suit, a bridge elevation with its text columns, and dense small-type classified advertisements for chemicals, lathes, telephones and bicycles. A designer could take the crowded advertising typography and boxed headline layouts as models for period commercial type and page structure.
