One of my favorite LEGO Architecture sets of the last few years have been the city skyline series, including 21028 New York City. LEGO architect Spencer_R specializes in 1/650 scale models of landmarks, including numerous skyscrapers. Spencer says he’d already built several of the buildings in the set, so he built the Flatiron building and Statue of Liberty, and then put all of them on a large black base. This much larger scale enables Spencer to include much more detail than the minuscule buildings in the official set, and the higher-resolution photo on Flickr — as well as Spencer’s photostream as a whole — is well worth a closer look.
