Batman (1991)
This year of Batman, while not having anything as flashy or headline-grabbing as some of the previous years (Year One, A Lonely Place Of Dying, A Death In The Family, Dark Knight Dark City, etc) is probably the most important year, for me.
I had already been reading Batman in UK reprints and collected editions (I still have my very well thumbed Death In The Family trade), plus I watched reruns of the 60s show and the Burton film, but this was the year that I started buying Batman myself, monthly, fresh off the racks.
463 was my first ever issue (actually part 2 of a 3 part story, but 11 year old me didn’t care about that).
So yeah, while this might not be a particularly important year from a “key” point of view, it’s arguably THE most important year for This Guy.
