Catalogus der schilderijen, enz. in het Stedelijk Museum "De Lakenhal" te Leiden / samengesteld door J.C. Overvoorde.
A 1925 Dutch museum catalogue of paintings and other objects held by the Stedelijk Museum De Lakenhal in Leiden, compiled by J.C. Overvoorde and published by H. Buurman for scholars and visitors. The two pictures are a printed inscription reading 'I. Potheuck, A° 1658' in a serif capital and lowercase style, and a bold woven-looking monogram of interlaced W-shaped strokes with a small star-like centre. A designer could take from them the period lettering with its swashed capitals and the dense, textured letterform built from repeated hatched strokes.
