This is a bird’s-eye-view of San Francisco with pictorial embellishments, drawn by James L. Delkin. Delkin seems to have produced variations of this map for an All About San Francisco series; perhaps the best known depicts war housing projects planned during World War II, along with illustrations of city scenes in red (see link in references).
The base map for our example is more elaborate and interesting, for example the Golden Gate and Bay Bridges are pictorially represented, as opposed to a simple lines on the other map. It also offers more place names and details within the city, along with more illustrations and pictographs throughout.
Our map is likely related to the 1939 Golden Gate International Exposition on Treasure Island, as there are several references to it.
