Similar To Pieter Schoubroeck (c. 1570-c. 1607) Copper Fantastic Landscape

Circle of Pieter Schoubroeck (c. 1570-c. 1607). A fantastic landscape, rarely seen, oil on copper, 13 cm x 18 cm (excluding frame). The work has been examined by a renowned restorer who confirmed that the composition, both in its material and the copper itself, dates from the late 16th or early 17th century, and that the work is a true cabinet curiosity. Condition: a little cleaning and slight retouching are needed. The buyer will receive the restored work, which represents about an hour's work, to restore its original splendor. (Photo before cleaning and of the back of the copper). Do you recognize the painter? I had also considered Anton Mirou and Frederick Van Valkenborch... Provenance: private collection, Krakow.
