Okay, this has "quota" written all over it, right? Somebody ran out of ideas for interesting necklines, saw her pinking shears, and, in desperation, hacked this one out.
Which is a shame, because once you get past "OMG WHAT BIT YOUR NECK??" the yoke on the skirt is really cute, and actually almost modern.
Anyway, it's from Lanetz Living (again) and you still have a few days to bid. You can certainly alter it to remove the sawtooth effect without too much trouble.
The other thing I love about this illustration is that it TOTALLY looks as if the woman in the red dress was originally a brunette, and that they drew a blonde wig on her. "Hey, there's no blonde on this envelope — blondes sell patterns!" "Just draw it on top. Nobody will notice." "It kinda makes her head look freakish." "I said, NOBODY WILL NOTICE!"
