I was walking through Penn Station in NYC this morning when I looked up and saw some great posters for AMTRAK. They were designed by Michael Schwab the great graphic designer. Michael was a judge for One Show Design this year. He's a really nice man and does amazing work. We've all seen his work, he's done work for just about anyone you can think of. I've always loved his posters for the National Parks. Simple and beautiful.
