Thanks to Alex, I just came across this amazing set of images by weetstraw on Flickr (do check out the rest!) Apparently, they are scans from a book entitled The Great Cities / Paris from 1977, and photographed by Raghubir Singh.
I always keep my eyes out for wonderful old books like this when rummaging through thrift shops (along with copies of National Geographic from the '70's) and while I've made some scores, I've never found anything quite this amazing. Ah well--to Amazon we go!
