Nettie Rosenstein for I. Magnin - 1956

I love a rose print.  Add a matching hat and I'm over the moon!  I. Magnin featured this dress by Nettie Rosenstein in a full page ad from 1956.  "we like the look of a rose on a stem...a big hat...a stem-slender dress by Nettie Rosenstein cut from rose-printed silk shantung, swept to the back and gently our Magnin-exclusive Rosenstein collection."  Perfection, pure and simple.  If anyone can tell me what the illustrator's signature says, I would really appreciate it.
