 Between 1960 and 1962 he began to produce his most significant body of work, which differed from the style of Israeli painting of the other members of “New Horizons” in everything connected to the inclusion of extra-artistic symbolic images.One of the things that motivated this burst of creativity was Aroch's exposure to exhibitions of the contemporary art of that period that were held in the Stockholm City Museum during those years.Among others, in 1962 Aroch attended an exhibition of the works of “Pop Art” artists, including Robert Rauschenberg and Jasper Johns.
