The Seoul subway is an enormous network that connects hundreds of towns and neighbourhoods. Passengers travelling underground have little visual connection to the urban areas passing overhead. Time and space are neutralized.

Hawkers target the subway system to sell their inexpensive wares to the captive audience on the train cars. By buying an object on the subway I am purchasing a souvenir of the area passing overhead. Time and space are fixed in the souvenirs, which are then attached to a Seoul subway linemap in their respective locations.
