LONDON—A small version of Renoir's La Loge ("The Theater Box"), one of the most celebrated Impressionist images, is being shown to the public for the first time since 1875, the year after it was painted, the London Times reports. Courtauld Institute Galleries in London is exhibiting it through February 21 alongside the full version, which depicts the artist’s brother, Edmond, and a model, Nini, at the Paris Opera. It is expected to sell for more than its estimated value of $6.95 million at Sotheby’s on February 5.
