Remember back in 1957 when brownstone Manhattan was being replaced by "new facades of gleaming aluminum"? (Actually, didn't that start in the late '30s?) Well Carnegie Hall wasn't safe from the building boom either, and this week Ephemeral NY reminded us of that now infamous rendering of a giant red skyscraper that was set to replace the hall. The image ran in a LIFE magazine article in September 1957; read the full article here, and a brief history of the Hall's near destruction here. Thankfully, the red giant never left paper.

Perhaps city planners and architects should keep a copy of this image on their drawing boards the next time they're starting to think about a new eyesore for the city's skyline?
