Sutcliffe, a talented painter, elected to quit the group and stay in Hamburg, planning to marry Astrid, but tragically died of a brain hemorrhage a few months after his bandmates went back to Liverpool.
The book, featuring black-and-white, cartoon-style art, looks interesting and benefits from input from Kircherr, herself.
According to Bellstorf:
"We both tend to think in pictures, she's a very visual person, and she basically liked the idea of seeing her story being told in little black-and-white panels.
"There was a kind of mutual confidence between Astrid and I from the very beginning, and I soon felt comfortable with telling 'her' story. I mean, love is such a universal thing, and of course I was touched by her tragic love story and could relate to this existential experience of losing someone so young."
