Jim,
I can't believe this escaped my radar. I love Harlan Ellison's work. I have a couple interesting items he produced, my favorite of which is a book called "Mind Fields" that is a collaboration with Polish artist Jacek Yerka, Morpheus Press. Really cool book of Harlan's fiction paired with some mind bending artwork.
Had no clue he was a pipe smoker.
RIP Harlan Ellison..
