Rick Tulka may qualify as an ex-patriot: he lives and works in Paris, France, and rides his bike to the same cafe, everyday, to have a coffee and sketch the local clientele. His sketches are exquisite and he garners loads of comments on each at his Flickr site.
Rick has a long and extensive history of showcasing his art, including working with such notables as Michael Jackson, and many, many more. He is also a cartoonist for Mad Magazine; and he has illustrated, "Paris Cafe: the Select Crowd," available at Amazon and well worth the price for anyone interested in the Paris Cafe scene.
Rick has also commented on many of the sketches I have posted on my Flickr site. In fact, I think he has commented there more than anyone else; so I consider him a mentor and friend, of an online nature.
He recently returned from a trip to DC - why anyone would go there in this dead winter is anyone's guess - I think mainly he went to the White House for a cup of coffee with Obama, but alas, was turned away. Poor guy.
