The bulk of the papers consists of incoming correspondence relating to orders and shipments from 1895 to 1920, and includes letters from all parts of the United States, Europe (especially England and Germany), and more distant places such as India, Australia, and Chile. The firm had important agents abroad, particularly A. W. Penrose & Co. (also Penrose & Co.) in London and Friedrich Hemsath in Frankfurt, Germany.

There is also extensive correspondence with Taylor, Taylor & Hobson, Ltd. of New York and Leicester, England; scientific instrument makers Bausch & Lomb Optical Co. of Rochester, New York; optical instrument makers Carl Zeiss of Jena, Germany; the Fuchs & Lang Manufacturing Co. of Chicago; and the Scovill & Adams Co. of New York. Copies of customer billing from 1907 to 1913 and bills and receipts from 1916 are among the papers.

Patents and related papers, 1888-1915 (58 items), include records of patents received by the Levys in the United States, as well as in Germany, Russia, Hungary, Spain, Cuba, Switzerland, Italy, Great Britain, France, Australia, Canada, and Belgium, all relating to their inventions in the field of photoengraving. Papers relating to the halftonometer invented by them are included, from 1912 to 1914; also, others concerning the civil suit of the Graphic Arts Co. vs. Hunters, Ltd., in the High Court of Justice, Chancery Division, London, 1910, with official testimony (188 pages) and supporting evidence (75 pages).

A few personal items are included, including letters of condolence upon the death of Louis E. Levy in 1919; lithographic proofs; dividend notices for the East Empire Syndicate from 1899 to 1900; some speeches and writings by unidentified authors, 1909 and undated; a resolution of the Franklin Institute, Philadelphia, and award of its Elliott Cresson Gold Medal to Louis E. Levy for his invention of the etchpowdering machine, 1907.

The correspondence, aside from orders and requests, deals with various aspects of the photoengraving business. That from Penrose in London discusses competition of other screens abroad. The elaborate letterheads of the various engraving companies are detailed examples of that art.
