Scale Drawing of 1960's Chicago TWA Time/Temperature Display
A scale layout of the time and temperature display that, from c.1963 to 1966, was part of the huge "spectacular" for TWA that was mounted atop the Shoppers Corner building at 150 North State Street (corner of West Randolph Street) in Chicago. This was a 7 x 11 numeral grid version of the 'TimeTemp-Sign' display as built by General Indicator Corporation, which 6 x 9 layout for the GM Futurama exhibit at the 1964 New York World's Fair can be seen here. The rows and columns appeared to be spaced 9" apart, thus PAR38 light bulbs would have been used. After TWA vacated the space around 1966, the individual sign elements including this remained dark until it (and the rest of the structure) was finally dismantled around 1970.
