 Since then, Gauguin evidently considered Theo van Gogh to be his dealer and promoter, and Gauguin also kept in touch with Theo's brother Vincent.When Gauguin finally accepted the proposition to live and work side to side with Vincent in Arles, he first sent a batch of recent work to Theo in Paris, who exhibited it together with the first batch of paintings sent from Arles, in November 1888.Around this time, Gauguin also received the invitation to exhibit with Les XX in Brussels, in February 1889.
