Brief aan onbekend Possibly 1932

"Brief aan onbekend" is a handwritten letter by Dutch art collector and dealer Andries Bonger, dated January 7th, 1932. The letter is written in French and appears to be a personal correspondence, possibly a letter of condolence. It is not clear to whom the letter was written, but the content suggests it was addressed to someone who knew Bonger and his late wife, "Etna." This intimate piece reveals a personal side of the prominent art figure, who was known for his work with artists like Vincent van Gogh.
