Other than the Custom House and JHT, Exchange Place was my favorite Boston skyscraper until One Congress.
It's hard to see it as being "dated," though I'm perfectly happy to concede it may, indeed, appear that way to some. Early/mid-'80s was when I first got interested in contemporary Boston architecture/development as a kid, so to me the tower still reads as being very current, cutting-edge, timeless. I recall older folks saying it looked "too Dallas" at the time and I thought that was parochial and narrow-minded.
Back on topic: great shots Dr. Rosen Rosen and #bancars!
