Both cover and interior art for this issue of Four Color is the work of Don Gunn, whose years as a Disney animator (late 1930s and early 1940s) are certainly put to lovely use here.
According to the inducks.org entry, Gunn worked for many comics companies, including Fawcett, American Comics Group, and Standard Comics; but his longest affiliation was with Western Publishing and Dell (1945 -1957) where he drew mainly Disney and Warner Brothers characters. Mr. Gunn passed away in 1972.
These last two pages are from the inside covers, both front and back. Dell often did black & white pages like these. They were done without color to save money, I imagine; but the fringe benefit for us fans is that we get a clear look at an artist's brushwork. Again - Gunn's Disney background is evident.
