This is an ad in an automotive magazine Motor Age, dated 1953, saying "DO THEY HAVE COMPRESSED AIR ON MARS? QUINCY COMPRESSOR, FIT INTO YOUR FUTURE".
This 1953 ad depicts a compressor that is almost identical to mine (which is a 1951 model).
58 years after it was made (it is 2009 as of the time of this writing), that compressor definitely fits into MY future. I bought this ad on ebay and framed it behind the compressor.
