Object record
Kol på papper, 26 x 17 cm, inklusive ram 54 x 44 cm. Signerad Cyrén. Gunnar Cyrén känner vi främst som glaskonstnär och silversmed. Till hans mest berömda alster hör Popglasen från sent 60-tal och Nobelservisens glas och bestick från 1991. Bland hans offentliga arbeten kan nämnas det förgyllda kors som han utförde i samband med den delvisa återuppbyggnaden av den branddrabbade Trönö nya kyrka, vilken återinvigdes 2001. Även om Gunnar Cyrén var glaskonstnär och silversmed, så utgjorde teckningen en grund för hans konstnärskap. I teckningarna kunde han utforska de idéer som sedan förverkligades i andra material. Att han var en driven tecknare framgår av auktionens självporträtt, där han med små medel lyckas förmedla både volym, liv och rörelse. Gunnar Cyrén är bland annat representerad på Nationalmuseum, Länsmuseet Gävleborg (där han har en egen sal), Röhsska museet, Nordiska museet, British Museum, Victoria and Albert Museum och Museum of Modern Art i New York. Has resale rights.

Automatic signature module
The local engine detects and isolates candidate regions, searches the trusted mark library and runs conservative signature forensics. Optional AI interprets unreadable regions and creates research queries without changing the forensic verdict.
The module runs during normal analysis when a local image is available.
Marks laboratory
110 independent methods generate cleanup variants, stroke and symbol descriptors, library matches, trust controls and conflict warnings.
Signature forensics
This does not declare a signature genuine. It measures fit against a multi-source reference set, confusing signers and natural variation.
Run mark matching first, then compare the questioned signature against a sufficiently broad trusted reference set.
