Linotype matrices;
A trade catalogue issued in 1913 by the Mergenthaler Linotype Company of New York, presenting its linotype matrices, the brass type-moulds used in line-casting machines, to printers and typefounding buyers. The three pictures show machined matrix blocks with raised character faces, a close view of a matrix-assembly mechanism with screws and a stepped escapement, and a bound row of matrices with rows of letters along the top edge. A designer could take from them the crisp, repeated geometry of type-casting parts and the stacked rows of letterforms as material for industrial or typographic motifs.
