Adventure Kartel mini-comic
From threeA Wiki
The Adventure Kartel mini-comic is a two-sided poster bonus that is included with every main Adventure Kartel figure release. On one side, it features a poster that is usually the painting from the box-art while the flip side features a single page mini-comic written and illustrated by Ashley Wood. These mini-comics provide a backstory to the figure(s) released in that series and often add more information that details the environment and situations occurring in the Adventure Kartel Universe.
