Thanks, outstanding, exquisite!
I believe he did this for Seventeen Magazine in 1967 and there were four drawings for different skin conditions: Normal, Dry, Oily, Combination. The two you show are Combination and Normal.
Hi Matt, you're right! he did indeed..I have that issue with all four of those illustrations from '67, they're fantastic. I'll post them in the near future as soon as I get around to photographing them properly (as the Seventeen mag format is way too big for my scanner). Because when you compare the ones from '67 to these French editions, the colours are quite different, particularly on the one for combination skin. I scanned them from Gebrauchsgraphik international January 71, but I think these particular ones were published in a magazine called Jardin des Modes while it was under the art direction of Jean Widmer (apparently he was the first to publish Milton Glaser's work in France)
