[GreenKeys] Skywriter

[Bruce Gentry]

       The actual Camel cigarettes the sign advertised were the real 
pollution and poison.  The sign used steam expelled from a specially 
designed chamber for the smoke effect, and operated for about 25 years 
into the 1960s. I think the changing nature of Times Square and  the 
public's changing reactions to tobacco  lead to it's demise.
