Ah yes, back in the good old days when the Earth was populated with the kind of colorful creatures that you’d have to drink a quart of Old Overcoat to see nowadays! :) I loved Bored of the Rings. I bet I’ve read it 5-6 times over the years. One of the funniest books ever, particularly for those who read the Tolkein books before discovering the Harvard Lampoon version.
I had an original print, like your photo, and a friend borrowed it and lost it. He bought me a far less desirable reprint that looks nothing like the original.
I never drink Old Overcoat, I prefer Old, Old Age.
