The Graphic Arts Collection recently acquired the collection of decorated and watermarked papers assembled by Ingeborg M. Hartmann (later owned by Jelle Samshuijzen). A description prepared by Sidney Berger is sampled here.
For over 40 years the German bookbinder Ingeborg M. Hartmann saved the endsheets and, in some cases, cover papers of the books she worked on, along with unprinted leaves (almost certainly flyleaves) containing watermarks. Today, her collection is housed in three custom boxes as follows: Box 1 contains 104 samples of decorated papers, mounted on 23 stiff archival board substrates; Box 2 contains 148 samples of mostly marbled papers, mounted on 42 stiff archival board substrates; Box 3 contains 142 unprinted leaves, each with a watermark.
This post highlights the watermark collection, which also includes two bound volumes that show the actual watermarks using beta radiography and drawings of these marks by Hartmann. No provenance information on the watermarked papers are given and the dates only generally listed 16th century to 19th century. The collection is not inclusive or definitive of any one place or time, but instead a gathering of fascinating, often beautiful examples. As with the printed and marbled papers, Hartmann has gathered hundreds of items to study and enjoy.
