Welcome to Disneyland's opening day! Presenting Disneyland features never-before-seen color images captured by a Disney studio employee, an invited guest of Disneyland on the day it was introduced to the world. This remarkable first-hand glimpse provides numerous candid, behind-the-scenes photos of Walt Disney and his new theme park as they prepared for their television and in-person debut. Previously lost to the decades, these photographs provide a visual history of the celebrity attendees, infamous "test wall" (before it made its way into the park), and overall excitement of what it was like to be in attendance at Disneyland on July 17, 1955.
