I'll drink to that

When most of liquor and fashion ads are looking just exactly the same in magazines, a few brands still manage to stand out. This week's winner has to be the Grand Marnier illustration ad on the back cover of this week's New Yorker. It's fresh, fun and giddy.
Nice job Grand Marnier!

I've been trying to find who the illustrator is but no success. So if anybody wants to share the info with me, please...
