"Penthouse"
Everybody's been passing that 70's time capsule around - it's NOT a penthouse, it's in one of the few non-lakefront high-rise complexes in Chicago, known as Winston Towers (1-5), often called Weinstein Towers (it's in West Rogers Park about as far as you can go north in that part of the city). The buildings were completed in the early 70's as condo's and were designed by a New Jersey architect (named Pancini iirc) and there is an identical building in Florida where, believe it or not, many people had identical units in both states. They have big units for the building type and were built on old truck gardens/garbage dump!
