Jean Colin (1881-1961) is a Brussels painter that is no longer known today because he often followed the way to realism. This way of painting, which while he was alive fully assured him success, has passed fashion and no longer draws art lovers. But Colin also left high level impressionist works that have no longer been shown since his death, works he painted for his own pleasure, conscious as he was that his conservative customers couldn't appreciate them. After Colin's death, most of his impressionist works were spread out between the members of his family-in-law or bordered in the museum reserves. This "tribute" is the amazing story of what happened to Jean Colin and to his hidden masterpieces.
