A small circular rubber stamp appears on the back of four panels in our survey of the Breda collection. Although smudged, the stamp appears to read ZOLI / I-5. It resembles a customs stamp although this is unlikely to be the case. Do you know the origin of this stamp?
Please note that although our main article deals with the forgery F198, our survey is of authentic works conserved by Adrianus van Loon. Note also that these stamps are entirely authentic.
