Contains a wonderful collection of digitised material, including very early films, one of which is reckoned to be the first automobile parade in New York, 1899.
Log in and search for automobile parade 1899.
Amongst the wonderful collection of cars is a Locomobile - I wonder who was driving - might even have been one of the Stanleys.
Searching for steam automobiles also produces a few photos of White steam cars. Enjoy
