These don't belong to Disney.
These Aida designs have been surfacing around as development art for a scraped Disney Feature production of Aida but it aint so. This was nothing more than a class assignment given out by Frank Terry when I was at Cal Arts back in 1996. (A couple of the characters were redrawn a few years later but the basic designs remained the same.) Frank brought in a newspaper clipping that Disney and Elton John were going to do an animated musical of Aida and our assignment was to create a line up of the main characters and give them all Disney style sidekicks. We then had the great Chen-Yi Chang come to evaluate the work which was pretty cool. In any case I posted them on my on-line portfolio and somehow they were mistaken for actual Disney development art.
