File:Between Nothingness and Eternity trade advert 1973.png

• US Copyright Office page 3: magazines are collective works (PDF)

Note that Columbia Records (CBS) did not put a copyright notice on their advert (e.g. © 1973 CBS Inc.). In addition, this photo is uncropped and unaltered. The lack of a copyright notice is true in some various Columbia trade advertisements that were carried out prior to 1974. After 1974, Columbia/CBS began adding the copyright notice in their subsequent advertisements. The only notice in the photo is a registered trademark notice of the author, Columbia Records (e.g. ..MARCAS REG...) on their advertisement.

• This advertisement was published pre-1978. The inclusion of a copyright notice was mandated until 1989; the author failed to include proper copyright notice, so therefore in the public domain in the United States.
