Thank you so much for opening the thread!
The last graphic novel I bought was Nick Cave: Mercy on Me by Reinhard Kleist,
which is probably for hardcore Nick Cave fans only.
Others I read last year:
American Vampire Vol.1
The Sandman Vol.1~Vol.3
Lucifer Vol.1: Cold Heaven
(I was lucky that I got all of the above from redditgifts exchanges!)
Dark Horse Number Ones 2017
The League of Extraordinary Gentlemen Vol.1
The first thing I'm going to buy if I ever win the lottery is Absolute Preacher and The Sandman Omnibus.
Three manga I'm still buying:
Anything by Taiyō Matsumoto and Naoki Urasawa, also JOJONIUM.
