His first solo exhibition, Nudes, occurred in 2000 in the foyer of Bucharest’s National Theatre. His next exhibition, Clocks, sold all 40 paintings on display. Many exhibitions later, Costin has become best known for his depictions of famous characters in the world of film, sport, politics and art, yet regularly departs into different experimental styles while retaining his originality and humor.
Today Costin is one of Romania’s most recognized contemporary artists, and has sold more paintings than anyone in the country. His buyers include Hollywood film stars, statesmen, ambassadors and businessmen.
