There are no closing credits of any kind. Not even the words "THE END" appear on the screen.
This is the second Walt Disney feature-length film ("Snow White and the Seven Dwarfs" was the first) on which the credit "Walt Disney presents" never appears. It appeared on all the other feature-length films that Disney personally produced.
The roadshow cut shows the title card at the intermission rather than the beginning, as on most prints.
Originally, the production credits were on a booklet distributed at the roadshow showings. They were finally put on screen for the 50th anniversary re-release.
The "Fantasia" title card for all releases prior to 1990 (including the original roadshow version) was slightly different from the one seen in the 1990 re-release and in the videocassette version. In the original title card, the letters spelling out the word "Fantasia" are of a slightly different shade of color, as is the blue background, and the title card reads "In Technicolor", just below the word "Fantasia". There is also an RKO logo at the bottom. In the 1990 version, there is no RKO logo, and below the title it says "Color By Technicolor".
The roadshow cut of the film features no credits or title music, just the Art Deco title card placed at the intermission. The general release cut (the one shown most often) places the title card at the beginning, as on most films.
