On a recent trip to Down Town Baltimore and to the prestine Longwood Gardens, I was able to see some mature American Elms. These are not Princeton, but I wanted you to see the size of the elms and the form of the classical elm shape that the Princeton will grow into with age.
This Mature Elm was in Downtown Baltimore very close to Camden Yards baseball Stadium. It was in a very old Church grounds, one of the historical churches there in the area. They have planted some Zelkova on the left and right of the elm some time back, but it is reaching up over the Zelkova and looked to be in good shape. This is one of the wetest Springs on record there in Baltimore and the trees looked very nice. 
This American Elm was located at the Famous DuPont Estate of Longwood Gardens. It was by far the largest Elm I have seen in person with a 4' diameter truck. It has your classical American Elm shape and was planted in the early 1930's. This is the last of the giant elms on property as DED has removed them all but this one. It has had some back truck damage on the right side, but seems to be healing over. This may be from a large portion of the truck being cut off or broken in a storm? If you get a chance to visit the estate and gardens, dont miss it. It was quite an experience.
