June 22, 1955: Walt with friend and painter Clyde “Vic” Forsythe and Mrs. Forsythe experience the near complete Main Street USA.
From the June 23, 1955, Los Angeles Times: 'Mr. Magic' in a pink shirt and old straw hat got ready yesterday to roll up the curtain on the impossible. It was costing him sweat and sleeplessness, but he was loving every minute of it. Walt Disney, in other words, is putting the finishing touches on the incredible dream-come-true that is called Disneyland. Right now, it all looks like king-size chaos. But says everybody who knows Disney, the $17,000,000 fantasy world will open on time Monday, July 18. Walt was on the prowl yesterday to make that certain… On the 160 acres of Disneyland, 1200 workers are swarming in a determined assault upon a job that should take another year, but is going to be done in 25 more days.
Growing up in Los Angeles in the 70s/80s we visited Disneyland on a regular basis and often after school, before "Annual Passes".
