• Note that the quality of the photo shown in the magazine is very poor and that this is an identical better copy of the photo.

• A search for copyright renewals was done at Copyright.gov. Three renewals were located for the March 29, 1952 issue, and they deal with individual articles included in the magazine.:

• Collier's, Mar. 29, 1952 Political zoo. By Clare Barnes, Jr. RE0000050310 1952
• Collier's, Mar. 29, 1952 Last time around. By Frank O'Rourke. RE0000043949 1952
• Collier's, Mar. 29, 1952 Political zoo. By Clare Barnes, Jr. RE0000050356 1952

• The magazine itself was not renewed and neither was the "Helter Skelton" article. There's no evidence that copyright continues to be claimed on this material.
