It was on the title card at the beginning of a "Steamboat Willie" cartoon that had just been re-released on a 1993 LaserDisc honoring Mickey's 65th birthday. It said in full:
"Disney Cartoons Present A Mickey Mouse Sound Cartoon Steamboat Willie A Walt Disney Comic by Ub Iwerks Recorded by Cinephone Powers System Copyright MCMXXIX." For Brown, it was as if the glass slipper fit him perfectly. The key was location of the word "copyright" in relation to the name "Walt Disney." There were two other names listed in between — Cinephone and Disney's top studio artist, Ub Iwerks. Arguably, any one of the three could have claimed ownership, thereby nullifying anyone's claim under arcane rules of the Copyright Act of 1909.
