I have a painting by Ronald Mallory of the Andrea Doria passing the WTC. dated 1981. The one that hung on the 107th FL of twin towers burned on 9/11 along with the twin towers. It was bought for 15K and I was wondering how much it would be worth now? the on that hung in WTC was dated 1982. There was only 5 I think of the paintings of the Andrea Doria by Ronald Mallory. I would greatly appreciate it if someone can help me with it.
