chocolate alphabet writing

Ordered a 1976 copy of Fantasy and Science Fiction so I could read Harlan Ellison's work: "From A to Z, in the Chocolate Alphabet." What a great title! Actually, my favorite part of it is his explanation of how it was written. He allowed himself to be walled into the front window of a bookshop where he wrote a different alphabet section every day, finally turning into a long nighttime session to the letter Z, while people wandered by the closed store and wondered at the maniac typing in the window.
