Does anyone remember the old cigarette ads that appeared in magazines
questioning the claim that smoking causes lung cancer? Their point
was: the correlation between smoking and lung cancer is not SCIENTIFIC
PROOF that smoking CAUSES lung cancer. Can someone locate an ad like
that for me?

Dear psusoc,

I managed to locate a such advertisement. It was part of a 1954 ad
campaign launched by 14 cigarette companies. The full-page
advertisement denying that there was any scientific proof for a
correllation between smoking and lung cancer appeared in over 400
newspapers on 4 January 1954.

Please follow this link to see a high-resolution scan [1] of the
original advertisement "A Frank Statement to Cigarette Smokers" (PDF
file for Acrobat Reader, 4 MB):

You can also read the full text here [1]:

In addition, here is another image of the advertisement (scroll down a
bit to see it). Unfortunately, the quality of this version taken from
old microfilm is rather poor [2]:

I hope that this is what you were looking for!
