Coryn Boel is copy after Saenredam

Hargesheimer, from Germany, sells on 22 September 2018 a "Circle of Coryn Boel" Corpora (vanitas) estimated at 2,000 Euro.

It is a copy after Jan Saenredam (after Goltzius), "An allegory on Vision (a couple of lovers)", as can be seen on this work at the RKD. As such, any attribution to the circle of a specific artist is dubious, and the estimate perhaps a bit high. I guess it is worth around 1,000 Euro instead, as it is charming from a distance but has serious problems when seen up close. No idea why Hargesheimer calls it a "corpora".
