I'm not 1000% sure this is the original, buuuut you can apparently buy the full comic here: https://www.giantessorient.com/store/p35/Gulliver.Zhou_English_Edition.html Not sure if legit, just what I could find.
Source links derp out when using HTTPS://, it removes the colon. You can manually add it back if it happens again on other images. I've changed the source for this to not use a secure connection. (HTTP instead of HTTPS)
