Note: Black FP letters in a white shield with a thick rounded black border containing the words"A Fox Feature Comic"

Note: Winking fox head in a circular logo with the text running in the border.

Note: FF in a shield with "A Fox Feature Publication" in a band around the shield.

Note: One known issue combines the back-cover Great Comic Library / World's Greatest Comics brand with the front-cover winking foxhead brand.

Note: This ribbon logo with a small star under it appears on the back cover of the one-shot surrogate-published by Larkin, Roosevelt and Larkin. It is identical to the "American Comics Library" back cover logo used on the one-shots surrogate-published by R. W. Voigt, except for the first word.

Note: Appeared on at least one of the 1944 giant issues published by one of Fox's surrogates (R. W. Voigt). This logo generally appeared on the backs of the issues, but on the issue of All Good Comics the front cover shows a boy reading the comic with both the front and back covers visible, and the very large back cover logo is clearly readable as a moderate-sized logo within the artwork of the front cover.

Note: FP in a black shield logo with no words surrounding it.

Note: Appears on the back covers of various giant-size one-shots. "Great Comic Library" appears along the top, then a "GCL" logo with letters intertwined appears in the middle, then "World's Best Comics" appears along the bottom. The phrase "World's Best Comics" also appears by itself on the front cover (only) of a 1947 issue. Additionally, the full back cover logo appears along with the more common winking foxhead logo (on the front cover) on a 1946 issue.

Note: This slogan appears by itself in very plain text on the front (but not the back) of a single 1947 one-shot (Everybody's Comics). The same slogan, paired with "Great Comic Library" and a "GCL" logo was used on the backs of various 1944 Wm. H. Wise-published one-shots, as well as the 1946 issues of Everybody's Comics, one of which recycled the 1944 cover and the other of which paired those slogans with the more familiar winking foxhead and was actually published by Fox Feature Syndicate.
