In 1947 Aroch participated in the Exhibition of “The Seven” at the Tel Aviv Museum of Art. At this exhibition ten works of his were shown, including “Men on the Promenade” (1943) and paintings of other scenes. Eugene Kolb published a flattering critical article on Aroch's work, and described his transition from Post-Impressionism to an emphasis on “constructed forms” and “simplicity of color.”[6] His works from the middle of the decade show a tendency toward schematism and the deconstruction of the scene into geometric parts in the style of the Cubists.
