These are drawn by Al Taliaferro. He began as an animator for The Walt Disney Studios in 1931 shortly before joining the comics department. He was an inker early on Floyd Gottfredson's run on the Mickey Mouse strip. After working on the Silly Symphonies strip, he began his run on Donald Duck. That gig would run for 30 years, from 1938 to his death in 1969.
He was the artist to originally introduce Donald's famous nephews, one full year before their appearance in the animated short Donald's Nephews. He also co-created other Donald Duck mainstays like Gus Goose, Grandma Duck, and Daisy Duck. Out of all the artists I've seen, Al Taliaferro is the artist who most closely captured the look of the animated shorts.
All of these are from Walt Disney's Comics and Stories Issue No. 115
