Yes, that pic looks much closer to ivory. I just noticed the color since I have had quite a few restored . I only use the year plate on the front because I get the antique plate from the DMV for the rear so I don't have to get it inspected.
If you ever want to have one restored, I recommend this guy in TN as he does immaculate work, just takes a long time...
