Dan Gormley was a principal artist for Dell's Four Color during the 1940s and 50s; and certainly one of the unsung names that made that historic comic so superb. He has become better known in recent years for providing a great deal of the artwork on John Stanley's take on Bushmiller's Nancy; but his best stuff came when working in his own highly individual style - usually on various Walter Lantz creations (like here with Oswald the Rabbit). This is from Four Color No. 183, March 1948; and Gormley did all the pages as well as this super cover.
More work from Gormley. These next two, one-color pages are from the front and back inside covers. These one-color inside covers (sometimes done in black and white as well) are one of my favorite features from this era of Four Color. I often wonder how many kids tried their hand at drawing for the first time, staring at the seductive lines of these inside covers.
