René Gruau Famous French fashion illustrator

I visited Paul Lacolley's who has some really nice art, who left a comment on one of my sketches, and he asked me if i was familiar with René Gruau, I did a search and found some work by this illustrator, and i love it, i do recognize some of his stuff but don't know that much about hime, so now i have something new to look up, only problem a lot of his books are expensive, so if anyone knows of where to find some of his art or book please let me know thanks, and thank you Polll
