Rarely Seen Maps From San Francisco’s Quirkiest Hidden Library

San Francisco, 1980

During the Cold War, both the U.S. and Soviet Union actively mapped the world, covering allies and foes alike. Rick says this map appears to be adapted from U.S. government topographic maps, such as those made by the USGS. But it was out of date even in 1980. Bay Area residents will note that Interstate 280 has some patchy spots about halfway up the peninsula, and there's no sign of BART, which began operation in 1972. Then again, it's hard enough to get your bike on BART, let alone launch an invasion.
