Interesting project. It actually depicts two unrealized dreams.
One of them is probably your inspiration, namely docking zeppelins on top of the Empire State Building. The other is the Larkin Building, which was planned for New York City, but never built. If it had been, it would have rivaled the Empire State Building, and the MacGraw Hill building would be an unrealized dream.
As for what might have been, all we have to go on is artists' renderings, but your building looks a lot like it.
Can't wait to see what it looks like with the zeppelin. Are you going to have a beacon on top of the mooring mast?
