And here are the two books as mentioned above from Miroslav Sasek, available here from Amazon.com
'This is Paris' brings one of the world's most romantic and exciting cities to life. Travel along the banks of the Seine and take in many of the wondrous sights that Paris has to offer: the Eiffel Tower, the galleries of the Louvre, the cafes, the artists of Montmartre.... how I would love to be there right now!
'This is New York' was first published in 1960, and Sasek's vision of the city at that time still remains fresh today. The hustle and bustle of Times Square, the wide streets filled with yellow cabs, and the awe-inspiring architecture are captured in his original and colourful illustrative style.
