Not Disney's Oswald the *Lucky* Rabbit but instead an obscure Dell comic from 1948. According to the excellent Big Blog of Kids' Comics:
Dan Gormley was a principal artist for 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 Rabbit). This is from Four Color No. 183, March 1948; and Gormley did all the pages as well as this super cover.
