Brooklands is the home of so much in the world of motor racing and powered flight. It has remnants of the first purpose built race track in the world, for a start. See more about the site here. This is a lovely print of a very striking original poster from the 1920s or 1930s.
These are all original screenprints. An original print is a work of art printed by hand, from a plate, block, stone, or stencil (which is the case here - screenprints are made using screen stencils) that has been created by the artist for the purpose of producing the image.
