One critic wrote that he was "a gifted technician who has made a sort of composite facsimile of the Renaissance school, he has every virtue except originality." In response to these comments, Van Meegeren published a series of aggressive articles in his monthly magazine "De Kemphaan" ("The Grouse"). Jonathan Lopez writes in his book on the forger that in the magazine he "denounced modern painting as 'art-Bolshevism,' described its proponents as a 'slimy bunch of woman-haters and negro-lovers,' and invoked the image of 'a Jew with a handcart' as a symbol for the international art market." Along with journalist Jan Ubink, this periodical was published between April 1928 and March 1930.
