Although Cornelis de Bie mentioned that Fruytiers also painted altarpieces, the only known works by his hand until the 1960s were works on paper or vellum. As a result, the established view about the nature of his work was not challenged. In the 1960s this view had to be revised, however, when three large paintings of saints dated 1652 with the monogram "PHF" (in the Royal Museum of Fine Arts Antwerp), which were previously attributed to a hypothetical painter PH Franck, were identified as being by the hand of Fruytiers. The same signature was subsequently discovered on another altarpiece in the parish church in Zundert, North Brabant, which had been purchased from the inventory of the dissolved Antwerp St Michael's Abbey in 1802. This led to the attribution to Fruytiers of other paintings in collections of the Royal Museums of Fine Arts of Belgium in Brussels, the Royal Museum of Fine Arts Antwerp and the Museo del Prado in Madrid, and in the parish church of Gistel, West Flanders. Drawings for some of his altarpieces are kept in the Plantin-Moretus Museum in Antwerp, the Yale University Art Gallery and the Kupferstichkabinett Berlin.
