"Toyland" is an 8-page Disney comics story drawn and lettered by Carl Barks.
"Toyland'" features Donald Duck, his nephews Huey, Dewey, and Louie, and Santa Claus.
[1] It was first published by Dell as a Firestone Giveaway entitled Donald and Mickey Merry Christmas #1948 (December 1948).
[2] Santa Claus invites Donald and his nephews to the North Pole to test the Christmas toys.
Donald has a rough time (he crashes through the roof on a pogo stick, for example, and is chased by a polar bear), but the nephews decide all the toys are wonderful and just what children want.
