Oppenheimer, who had officially adopted the artist’s name, MOPP in 1919, was now able to move back into his old atelier in Joachimthalerstrasse in Berlin. A series of exhibitions at the Galerie Caspari, Munich, the Galerie Arnold, Dresden, and at Paul Cassirer’s ensured he received the attention for which he had hoped. Aside from a number of articles, which were published in various art periodicals, the Werkkunstverlag dedicated a double issue in its art archives series to his works, with articles by Max Osborn, Alfred Stix and others. Thomas Mann, whom he had painted in early 1926 (cat. raisonné 166), became aware of his large ‘Orchestra’ picture and published an enthusiastic essay on it in the Berliner Tageblatt. This increasing regard assisted Oppenheimer, and the city of Berlin and several museums made a number of purchases of his work...

Without aiming to be socially critical in his work, which he oriented much more towards the unpartisan, realist painting of the Neue Sachlichkeit in terms of subject matter, Oppenheimer does convey modern people who mirror the dynamic, vibrating metropolis in his paintings from this period. He wrote on the subject of his portraits dating from these years, “... the favourably composed man, placed within a space, is not enough for the portrait painter of today. The sitter’s surroundings impinge, the room, the street, the city. Things that cannot be perceived optically intensify the portrayal of the man of today. His attributes have disappeared, emblems have been eliminated. In their place the surroundings and objects play a symbolic role. A product of the great cities, the nervous man, chiefly considered as an object, requires new, emphatic means of expression. ...’
