Portrait of a Young Gentleman is a c. 1635 painting attributed to the Dutch painter Rembrandt.

[1] The painting was discovered and purchased through an anonymous investor by Dutch art dealer Jan Six.

[2][3][4][5][6][7][8][9] Jan Six lives in Amsterdam and showed the Christie's catalog entry to Ernst van de Wetering before booking a ticket to London to attend the sale.

His main clue was the tentative date in the sale catalog of "1633-1635" while it was attributed to "circle of Rembrandt".

The son of the restorer, Dutch art dealer Sander Bijl, had also noticed the Christie's catalog entry for Portrait of a gentleman, half-length, in a black velvet cloak and white lace collar and cuffs and had approached Six with a plan to buy the painting together.
