While it's a collaborative effort, here are some key figures involved:
* Walt Disney himself had the initial vision for the attraction, inspired by the "small world" theme at the 1964 New York World's Fair.
* Mary Blair, a renowned artist, was heavily involved in the design, creating the vibrant colors and whimsical characters.
* Harper Goff, a scenic designer, helped bring Mary Blair's designs to life.
Overall, the "it's a small world" attraction is a testament to the collaborative spirit and creative genius of the Imagineers at Walt Disney Imagineering.
