Space Needle Rendering, Paul Thiry
Great renderings of Seattle’s 1962 Century 21 Exposition; Paul Thiry was appointed principal architect in 1957.
Here is a 1983 interview with Thiry prior to the announcement of winning the AIA Seattle Medalist 1984 (interesting stuff).
Anyone else have links to cool Mid Century Modernist renderings?
