Gon - Ch. 1 - Gon is Very Sleepy

Sweet that there's no watermark but the colour's really fucked

These are color chapters, which seem to have not been reprinted in the JP volumes for whatever reason. They're included in the Spanish version, and probably other editions such as the recent Italian release (Spanish is scanned and on Nyaa). This is a scan of the 1998 release (by Trango-POPS?). The Spanish scan has better colors but is still a bit overblown.

There's also a 2013 98-page chapter.

And Wikipedia says there were "Colored Gon" chapters in 2013, but I don't know if those are the same as these.
