During his army service Struck created some four hundred prints, mostly lithographs, depicting the life and culture of East European Jewry. The portraits and landscapes were published after the war in a number of portfolios and publications, most notably The Face of East European Jewry [Das ostjüdische Antlitz], 1920, with an essay by Arnold Zweig. Zweig drew a somewhat rosy picture of a community that he perceived as vital and authentic, hoping to persuade the German public to revise its mostly negative opinion of the displaced East European Jewish population that was pouring into Germany, resulting in acrimonious debates over the ?Jewish question?.
