Bylaert, Joannes Jacobus (1734 – 1809). (Also as Bylaerd and Bijlaert). The Egg Seller. 1770. Image: 21.4 cm x 17.8 cm; sheet: 22.4 cm x 18.6 cm. A chalk-manner engraving with red and black ink, on laid paper with a partial watermark. The upper left-hand corner has been replaced, and the lower left-hand corner is slightly stained from a prior mounting glue. Some foxing and staining are visible on the verso. There is a manuscript inscription on the verso in Dutch dated 1770 and signed “J. J. Bijlaert” using the word “Tekening.” Bijlaert’s process used to produce this engraving is a combination of crayon and stipple techniques, as he used a method of dotting with points (poinçoins) of various sizes to obtain the texture. His aim was to create the texture of chalk. Not in Wurzbach. See Hind, A History of Etching and Engraving. Dover, 1963; pp. 289-90.
