Gwandanaland Comics the title is published by Gwandanaland Comics the publisher. It's a series of trade paperbacks reprinting public domain comics from the 1930's to the 1960's. The subjects are different from issue to issue, but all have a Gwandanaland Comics issue number, making it a series.
Note on the cover dates: Gwandanaland Comics publishes this series through a Print on Demand service. They have a long list of books they want to put out, and they get numbered as they're added to the list. So they're not necessarily released in numerical order. They also release multiple books per month. Therefore dates will be all over the place, starting in 2016, and you may see multiple issues with the same cover date.
