Ocean Park was built in Santa Monica, CA in 1958 and closed in 1967. It was a very large park that was built to compete with Disneyland. However, city planners, in an effort to renew the area, demolished buildings and closed streets all around the park so people couldn't find there way in. Even though it was a huge park, it was forced to close it's doors and the contents were auctioned off in 1968. These cards are marked "Pacific Ocean Park Arcade 1¢" on the front and have a postcard back.
