Los Angeles International Airport Theme Building, designed by Pereira and Luckman and Associates, Welton Becket and Associates, and Paul R. Williams, 1961, Los Angeles. Designed by a partnership of three of the city's major architectural firms as the centerpiece of Los Angeles International Airport, the space-age Theme Building symbolized the city's optimistic view of the future. Rust damage to its stucco-clad steel parabolic arches caused a one thousand pound chunk of stucco to fall from one of its upper arches in 2007, leading to a complete rehabilitation and seismic retrofitting. The structure is seen here in 2005, prior to that rehabilitation. Photo: 2005, Gail Ostergren, GCI.
