If you’ve ever marveled at the fantastical facades of Disney’s "It’s a Small World" attraction, you can partly thank Imagineer Rolly Crump. Throughout the 1960s, the animator and designer helped bring to life some of Walt Disney Parks’s most iconic attractions, including the "Enchanted Tiki Room," "Haunted Mansion," and "Adventureland Bazaar."

Later this month, some of his original pieces will go under the hammer at Van Eaton Galleries in Sherman Oaks, California. The most valuable of the 400-plus lots is Crump’s original model for a clock in "It’s a Small World," which could sell for up to $80,000, according to the auction house. The design was mocked up from fellow Disney artist Mary Blair’s original sketch, and the end result is now a permanent fixture of the boat ride attraction.

A few other items up for grabs are a Polynesian-style shield that Crump sculpted for the "Enchanted Tiki Room," an original devil prop from "Mr. Toad’s Wild Ride," an original "Haunted Mansion" poster, and a costumed character head from "Babes in Toyland." A ticket for the grand opening of Disneyland in 1955 is expected to sell for as much as $5000—although unfortunately it won't grant the buyer entry to the park these days.

In addition to pieces created for Disney, the collection also includes Crump’s original artwork, some of which dates back to his high school years. One such illustration of a colorful character wielding a sword and smoking a pipe was entered into a radio contest in 1947 by Crump’s mother, unbeknownst to her son. He didn’t win, but his consolation prize came five years later when he was hired to work at Walt Disney Studios at age 22.

The “Life and Career of Disney Legend Rolly Crump” auction is scheduled for April 28, 2018.
