Mies with Fritz SchŸler, Electric Utilities Pavilion, International Exposition, Barcelona, 1929

Interior covered with large-scale photographs depicting various aspects of the German power industry; gave illusion of 3D panorama, opening the space toward an imaginary horizon (novel wall treatment, rather than typical plaster cladding)
* some photos even wrapped around corners to dissolve perception of a limited space
large-scale images emulated a real view and transformed the boundaries of architecture
