Preliminary study for Schouman's picture dated 1750 in the Municipal Museum, The Hague.  Maria Arnoudina Gevaerts was a daughter of Paulus Gevaerts, mayor of Dordrecht, Schouman's home town. In 1749 she married Jacob van der Heim (1727-1799), which may have been the occasion for which the painting was commissioned.
