opening panel of the first daily The Spirit comic strip from October 13, 1941 by Will EisnerThe estate of Will Eisner is putting the entire output of Will Eisner that they control through copyright and trademark up for sale, including The Spirit and all of Eisner’s graphic novels and comics. George Gene Gustines for The New York Times reports (or here):Up for grabs are Eisner’s graphic novels, children’s books and instruction manuals for creating comics. Eisner’s last work featuring the Spirit, a 72-page story from 1996 called “The Spirit Returns,” was never published. The Spirit by Will Eisner, The News of Boca RatonThe only Will Eisner Spirit comics never collected, and still under copyright as I would assume every other Spirit story since the 1960s, is the short run of the daily comic strip he did for The News of Boca Raton in 1991/92. But that does leave a wealth of Will Eisner material in the form of graphic novels and historical writings, including The Spirit from the 1960s until his death.
