There's a great piece on Intelligent Life explaining how Bob Dylan's first major art exhibition came to be in Chemnitz:
Persuaded of Dylan's talent as a draftsman, Mössinger wanted him to "eventually complete" his sketches—something he had indicated a desire to do in his book's preface. It took her a while to get hold of him, but once she did, she received a positive reply within two days. Dylan was inspired by her commitment. "I was fascinated to learn of Ingrid's interest in my work, and it gave me the impetus to realise the vision I had for these drawings many years ago. If not for this interest, I don't know if I even would have revisited them", the singer is quoted as saying in the museum's literature. Over eight months Dylan elaborated on his 322 works.
