Editor Curtis again privately complained to Nast about his pictorial attack on the anti-Grant liberals, but the artist's assault not only continued, but intensified. Curtis was not alone in his assessment. Throughout the year a great deal of ink was devoted to criticism of the work of the two major national cartoonists, Nast and Matt Morgan. Their special discipline of caricature, the portraiture of distortion as a vehicle for personal attack, struck many editors as particularly wanton. As early as May 12, the Boston Gazette warned readers about the excesses of "Caricature In The Canvass," and how it was throwing all caution and restraint to the wind: "The Presidential campaign of 1872 is likely to be memorable for the pictorial features of its warfare. … There is an outrage upon propriety … which it is the duty of journalism to rebuke in no uncertain tone." As the campaign wore on, the Brooklyn Eagle, the Washington Daily Patriot, the Chicago Inter-Ocean, Atlantic Monthly, and other periodicals joined in the condemnation.
