The sheer size of the vast advertisements dwarfs their neighborhood. This reminds me of "Gulliver`s Travels" (by Jonathan Swift), especially to the "country of Lilliput". There he meets tiny people, the famous "Lilliputians".
Often houses, people and carls look lilliputian compared to the megasized billboards.
Here a collection of pics capturing this Lilliput Effect. Here you can see another collection of fascinating billboard pics (driveby). Enjoy.
