This drawing, depicting a group of houses, was previously given to Jan Asselijn (Dieppe, 1610-Amsterdam, 1652) and auctioned as by Jan Frans van Bloemen "Orrizonte" (Antwerpen, 1662-Rome, 1749), though both attributions are unsure.
Another attribution to Herman Saftleven was mentioned, but this also is unsure.
Though the attribution remains a mystery, the drawing shows great draughtsmanship by a Dutch School artist, ca. 1650.
