Vincent painted this self-portrait in September of 1888. It is now owned by Harvard University.
At Harvard's art museum web site, we learn the following interesting information about this work:
"Vincent
van Gogh arrived in the small town of Arles, in the south of France, on
20 February 1888. The next fifteen months were the most prolific in his
short career. Although he sold no pictures, lived in poverty, and
suffered recurrent hallucinations and depression, he still managed to
produce some of his best work during this period.
"He worked at a staggering rate, often exceeding fifteen paintings a month.
"Van
Gogh's friend, Paul Gauguin, agreed to come to Arles in June 1888, but
did not arrive until October; meanwhile, they had exchanged
self-portraits. The two artists later parted after a famous quarrel.
"Van
Gogh's gift to Gauguin, the celebrated Self-Portrait Dedicated to Paul
Gauguin, now hangs in the Fogg Art Museum [at Harvard].
"...Preparing
the painting for restoration in 1980, the conservators discovered that
the work had been damaged and then restored by an unknown hand.
Tracking down the clues uncovered by the conservators, art historian
Jirat-Wasiuntynski concluded that these early restorations were by
Gauguin himself."
