A multigraph was a combination type-setting and printing machine.[1][2][3] Multigraphs were typically used to produce multiple copies of a document (similar to how photocopiers were used in later decades).[4]

E. Wheeler Multigraph Machine Co., an American No-Maj company that made and/or sold multigraph machines, had an office on the second floor of the Woolworth Building in New York in 1926.[5]
