I have to apologize to Rocco Butliere. I had thought that he had simply made a bunch of copies of Spencer Rezkalla's various buildings, so I had kind of ignored him, preferring instead to feature the originals by Spencer. But even when Rocco took on the same subject matter as Spencer, he came up with his own designs. At the recent BrickWorld, Rocco and Spencer teamed up, joining Spencer's World Trade Center complex (featured here before with Rocco's equally great World Financial Center. All of Rocco's work can be found on MOCpages and Brickshelf.
Here's a picture of Rocco and his skyscrapers. I'll definitely be sure to not pass him by again.
