One of those artists was J.F. Kernan (1878 - 1958). Just like Rockwell, Kernan's work focused on middle-class life in America, or as he described it "the human side of outdoor sports, hunting, fishing, and dogs." He was born in Massachusetts & would attend the Eric Pape School of Art in Boston & even teach there for a while, too. His work would appear on the covers of most major magazines between the 1910's to the 1940's. His art was seen on the covers of such periodicals as The Saturday Evening Post, The Country Gentleman, Outdoor Life, & many others including different calendars & advertisements of the time.
Below are a few of his works that I really like. His sense of humor & artistic abilities really make these works enjoyable. You can almost step into these scenes yourself.
