Issue #17, 1999: the one where Luffy and the gang walked to Arlong Park, JoJo classic concluded and Yabuki was debuting with a later axed manga.
Issue #12, 2005: the one where the battle between L and Light had a winner, Matsui debuted with Neuro and many other series delivered their own historical chapter.
Issue #22, 1985: the one where I tried reviewing an issue of the '80s and it was so difficult that I swore to never do that again.
Now updated!
Issue #45, 2011: the one where I wanted to cover a pivotal chapter of HunterXHunter, but I read the wrong issue and got a pivotal chapter of Naruto instead.
Issue #15, 1991: the one where a certain Saiyan turned his hair blonde for the first time, and the history of manga changed forever.
Issue #48, 2008: the one where Jump didn't care to celebrate its 2000th issue, but there are a number of historical chapters anyway, most notably Bleach is about vice-captain Omaeda.
Issue #33, 1997: the one where it was the last time we lived in a world without One Piece, and I thought it would be an easy issue to cover but there are too many unfound chapters.
Issue #43, 2011: the one where I corrected the mistakes of the past and covered the issue with that pivotal chapter of HxH, where we mourned the loss of a King.
Issue #41, 2001: the one with the weak motivation of being the last issue of Jump before 9/11, but at least it contained some gems like the 5th chapter of Bleach.
Issue #29, 2017: the one where a beloved Pillar says goodbye at the end of the Mugen Train Arc, and six consecutive series just debuted, all of them notable in different ways.
Issue #41, 1993: the one where YuYu Hakusho gets cruel with kids and nothing else was particularly impressive, sign of a transitional era for the magazine.
Issue #6/7, 2015: the one where Gintama lost an important member of the cast, and Tamura delivered a one-shot between Beelzebub and Hungry Marie.
Issue #29, 1990: the one where I finally had the chance to write about one of my favourite all-time series, Saint Seiya, and also Goku uses his mind-reading technique for the first and only time.
Issue #46, 1981: the one where I was tempted to go through the first Jump with 10 reviewable chapters, finding the first episode of Black Angel and some good classics like Cat's Eye or Dr. Slump.
Issue #36, 2003: The one where Death Note debuted as a special one-shot, tons of battle shonen are thriving at the same time, and Jaguar won the contest for the
panel of the week.
Issue #1, 2010: The one that kickstarted the decade of the '10s, with One Piece Strong World heavily promoted any many future succesful authors trying their shot with a not very succesful series.
Issue #7, 1987: The one where Dio Brando went too far after five chapters from his debut, and Kinnikuman was so '80s weird that it has to be seen.
Issue #30, 1995: The one with the special manga biography of Roberto Baggio that unfortunately couldn't be reviewed, but at least Bonbonzaka ends and a Yakuza bets his arm on a new era.
Issue #25, 2013: The one when Kochikame was finally translated (apparently by AI) and I reviewed a whole issue because of that; an issue with a game of Lacrosse and Soul Catcher(s).
