According to the Leupe catalogue (NA), the original title reads: "Afbeeltzel van 's Comp:s Fortresse Henricus, op 't Eylant Zolor". Belongs with the description of the billets at Solor and Timor by Arnold de Vlaming van Oudtshoorn. Notes on reverse: "233" likely refers to the folio number in the OBP volume / "602 i".
