Painting considered workshop copy is in fact by Rembrandt, expert says
Exclusive: UK owner’s version of Old Man with a Gold Chain reunited in Chicago with undisputed work by Dutch master

TL;DR
- Scholar Gary Schwartz claims a UK painting, "Old Man with a Gold Chain," is an original Rembrandt, not a workshop copy.
- The painting is nearly identical to an undisputed Rembrandt version owned by the Art Institute of Chicago.
- Schwartz argues that Rembrandt, like many Dutch artists, created replicas of his own popular works.
- Scientific analysis shows the UK version's canvas and pigments match Rembrandt's materials and techniques from the period.
- Despite initial assessments by the Art Institute of Chicago suggesting a reproduction, the debate over the painting's authorship continues to evolve.
