Leading up to The Overstreet Comic Book Price Guide #50 release, Gemstone Publishing will commemorate the milestone by diving into the publication’s rich history. Over the Guide’s five decades in print, thousands upon thousands of comic books have been priced, the market has been meticulously studied, and creators, characters, and publishing houses have been featured with detailed coverage. With the 50th edition comes time to revisit how comic values have steadily (sometimes astronomically) risen over the years and reflect on contributions made in crafting the Guide.

Issues that contain the first appearances of characters in comics are important. But while some can be recalled with rapid fire speed, others take a little more thought or research. When it comes to superheroes’ best pet buddies, the latter is often true. Which is why in The Overstreet Comic Book Price Guide #28, Robert M. Overstreet compiled a list of the important first appearances of several super pets. Below is the list of super pets featured in the 28th edition of the Guide.
