This is Minnie's last major appearance in a Mickey Mouse cartoon until Mickey's Christmas Carol (1983). She would, however, make a brief cameo in Pluto's Christmas Tree (1952).
The animation of Pluto tussling with the top hat is reused from Mickey's Grand Opera (1936), while the animation of Mickey trying to dodge traffic is reused from The Country Cousin (1936) with Mickey in place of Abner Countrymouse.
"Mickey's Delayed Date" from 1947 is the only Mickey Mouse Cartoon released in 1947 and is the second and final appearance of Mickey in this year. The first was in the "Mickey and the Beanstalk (1947)" segment of the 1947 feature film "Fun and Fancy Free (1947)".
