Pretty impressive the work of Dan Palatnik, brazilian ilustrator, specializing in digital art.
Thanks to illustrators like him, the industrial design of past decades is kept alive, so the new generations can admire it, and realize how art could be applied to industrialized products.
His collections of radios from the 50's and 60's, on the illustration down bellow is amazing.
Palatnik also has a very extensive collection of automobile illustrations ranging from the 30's to the 60's.
