When it comes to South Side Copycats, the buildings are usually spaced well apart. In this case, the folks involved shot their entire wad at one intersection. Two identical (and massive) buildings mirroring each other from across the street.
I have been at this intersection dozens of times without ever noticing the mirror effect. It took this brilliantly sunny summer morning for me to finally see this odd and beautiful sight.
