Yes, there was a time when this drawing was correct: Great America was owned by Marriott, and there was a theme park called Marine World in Redwood City.
Hotel company Marriott built Great America and its sister park (also called Great America) but eventually sold off both parks. Neither of them have “Marriott” in the name anymore.
Marine World merged with another park and became Marine World/Africa USA. The park moved to Vallejo in the mid 80’s and eventually became Six Flags Discovery Kingdom. The former location in Redwood Shores is now home to Oracle and a few other tech companies.
My, how times have changed!
