I didnt understand the lolipop reference because I dont remember that sculpture and thought one could construe the building's shape as pregnant but yea now that you mention it thats 100 federal I guess. Again, it doesnt matter much as fewer and fewer people see the building as significant in any way which is my point.
Per this blog, the lollipops installation was on-display from circa 1975-2000. Being at 100 Summer St. Plaza, obviously it wasn't too far away from 175 Fed...
