Craig-
Thanks for posting. Great card. If it ever needs a new home...
The majority of 150's don't show the Doves at all or only some bits and pieces of them. The best one's that do like the high grade I posted from the Legendary auction or the proof that you posted are still not as deep in color as the 350's.
Some 350's don't show the Dove like my Piedmont 350 but they are not the norm in the series. Most do have the deeper colors like Ted Z stated he has seen across the board in the 350 series.
