San Francisco Bridges postcard booklet

Appropo of the 11th Street Bridge Park project, which I wrote about yesterday, and the posts from July and August ("The Anacostia River and considering the bridges as a unit and as a premier element of public art and civic architecture" and "Saving the South Capitol Bridge as an exclusive pedestrian and and bicycle bridge") arguing that the city could address bridges across the Anacostia River in a much more significant and design-forward manner, I came across a souvenir postcard folder from the 1930s, focused on how "The World's Greatest Bridges span the San Francisco Bay."  One side is devoted solely to the Golden Gate Bridge and the other side pictures the other bridges.

I imagine there are bridge-focused folders for other cities, so I'll have to be on the lookout for them.
