Preview detail from “Displacement,” the travelogue comic about going on an elderly cruise trip with my grandparents last february. This week I’m trying to finish up the last of the colors on this book. Even though I know it all happened, reading these pages again, it all seems so incredibly unbelievable. Did I really almost get into a fistfight with that giant awful guy? Did I really get barfed on by all those people? So many things to re-live, in glorious watercolor.
