Documents published without copyright notice in the United States before January 1st, 1978 are in public domain in that country.[1]
They are also in public domain in the European Union, where the "shorter term" rule applies to foreign works, and foreign documents which are already in public domain in their home country are not further protected.[2]
The advertising material inserted by a company in a magazine usually does not have a copyright notice. It is sincerely believed by the Camera-wiki members who discussed this question that the copyright notice which might appear on the magazine itself, on behalf of its publisher, does not extend to the advertisements, on which the publishing company owns no right and which would be the property of the advertising company if it wanted to claim its rights.

Argus for color, Mar 40 PopPho inside back cover pg. 123

Image by camerawiki
Kodachrome as a 35mm still film had only been available for 4 years when this ad appeared. It was not available as a paper-backed roll film, and so it had a big stimulating effect on the market for 35mm cameras—which this Argus ad capitalizes on.
Also interesting is that several manufacturers in this era used the term "candid cameras" generically for their smaller 35mm models.
I’d also like to point out that Argus calls the camera "C-3" here (with a hyphen), just two months after using "C3."
