Brickstructures sells special edition microscale models of famous skyscrapers, complete with instruction booklets and — I think — boxes. The current set is the Empire State Building* (a building I love so much I pay a bit of a premium for my CPA, because her office is there) and the Space Needle. Both can be had together for $60, shipped.
The builder also makes larger scale models that aren't to be missed.
