A collection of roughly 6,500 blueprints, architectural drawings, sketches, and photographic documentation of the construction site of the Union Station in downtown Los Angeles made between 1932 and 1939. Includes: conceptual drawings; landscape drawings; sketches of exterior and interior views; detail drawings of architectural elements, materials and furniture; plumbing and electrical working drawings; landscape drawings; and photographic documentation of the construction site (mostly negatives and some small black-and-white prints). The principle architects for the project were John (1861-1935) and Donald Parkinson (1895-1945), a father and son team who also designed the Los Angeles City Hall. There is also a logbook containing an indexed record of the drawings by section (not all drawings are listed in this ledger), and original plans accompanying the contract dated April 23, 1937 covering Main Station Building for Los Angeles Union Station Passenger Terminal with Robert E. McKee, general contractor.
