Disneyland’s Three Season Passport was the Ultimate Status Symbol in 1985. This special card for a Three Season Passport was a benefit for Hollywood Bowl Patrons. It's sort of an Annual Pass, but just for three months. Those are the three months that Disneyland has the least amount of visitors (in 1985). January and May are still slow months, weekdays in early May are my favorite times to visit the park (expect plenty of trips reports). September is pretty slow too, after school starts!
The scan and your screen are not blurry, it’s the card. It was printed on think shinny paper that’s solid black on the back. I’m thinking there has been some bleed thru over the years, that or it’s a bad printing job!
And for some color and non-blurriness, here's another undated souvenir slide of Alice and the Rabbit. I like the new Alice better... Be sure and visit Vintage Alice Disney.
