I don't know about you, but I have my favourite pattern envelope illustrators. They aren't credited (as far as I know), but certain works always catch my eye. Take these Very Easy Very Vogue illustrations below:
I don't particularly love the patterns, but I am always "hearting" them on Etsy because there is something so attractive about them. Then I realized that they all appear to be drawn by the same artist.
On the other hand, you probably recognize the woman in these bizarre McCall '70s illustrations. I call her The McCall's Cutie: Fake-and-Bake tan, too much rouge, too much teeth, too vacant a stare....
What about you? Are there certain envelope patterns that inexplicably draw you in because of their art? Is there any way to find out the name of the illustrator for a particular series of envelopes?
