None of the reprinted stories in this volume have creator credits listed, despite some of them having credits listed in their original publications. Roughly half of the features in the original issues did not carry credits either.
Comparing the original publication credits with those listed on this volume's cover identifies one creator, Vincent Waller, who was not credited in the original issues. (At least, he was not in the stories that are reprinted here - the collection is incomplete.) His name has been added to the general listing until his contributions may be identified.
The second panel on page 30 has been changed from its initial publication. In the original printing, the illustration featured a cartoon of Dark Horse publisher, Mike Richardson. It has been replaced with an image of George Liqour & Jimmy.
