This is a photo from Disneyland probably taken in the early 1970s. It depicts an attraction called The Peoplemover. It was meant as a demonstration of futuristic technology, suitable for moving people around urban centers, airports, shopping malls and what not.
It was introduced in 1967 and took the passengers for a ride around Tomorrowland at Disneyland in Los Angeles, with the light weight tunes of Buddy Baker playing in the background. The ride was unfortunately closed in 1995.
