One of the great developments of the Dieselpunk era is the outstanding poster art - always an easy sight to enjoy and inspire. There are a handful of modern artists who have the talent and vision to emulate the style of the era - one of my favorites is a superb gentleman named Mr. Lipatov.
Mr. Lipatov is a bit of an enigma, as the extent of the information I was able to divine is from his location on Deviant art. However, his outstanding work is amazing to behold. He has a knack for melding genre vehicles (e.g. trains, airships, hovercars), with lovely ladies (including a few risque works on his Deviant art page)...
I would certainly recommend a trip to his virtual outpost, to see more of his amazing works! To do so, please follow the link, and you will be agog at the work! His locale is found at: http://lipatov.deviantart.com/
