It was any cartoonist's dream assignment: go to Europe, as a tourist, and draw and report on what your experience is like.
This happened to Ludwig Bemelemans (the guy who did the MADELINE books). The editor of HOLIDAY Magazine asked him to fly to Europe, to see how the people were doing. This is just after WWII. Certain cities were in rubble. The Marshall plan was rolling out.
"After the most casual arrangements and without writing anything down on a contract form or even the back of a menu, I left, virtually from the table of the restaurant at which Ted Patrick [his HOLIDAY Magazine editor] suggested the voyage. I traveled wherever I would have gone had I been on my own holiday. I stayed everywhere as long as I liked."
Here are a dozen of the fifty color illustrations and 100 black and white illustrations from his collection of essays, THE BEST OF TIMES, copyright 1948 by Simon and Schuster, Inc.
My copy fell apart (the back cover came off while scanning these). It's easy to find online at used book sites, but most copies are well read. You can see why.
