Translations:Commons:Copyright rules by subject matter/6/en

 Not OK General rule.

This 1973 advertisement for calculators did not have a copyright notice and is in the public domain.

OK Exceptions: In the United States, advertisements published in collective works (magazines and newspapers) are not covered by the copyright notice for the entire collective work. (See [$1 U.S. Copyright Office Circular 3], "Copyright Notice", page 3, "Contributions to Collective Works".) This is because the same advertisement will often run in many publications. (See [$2 U.S. Code title 17, chapter 4].) Note that this rule does not apply to advertisements whose copyright belongs to the publisher of the collective work, such as ads for another magazine subscription. It also does not apply to advertisements first published outside the United States.
