The Baron Rides Out (illustrated by Patrick Benson) 1985, The Baron on the Island of Cheese (illustrated by Patrick Benson) 1986, The Baron all at Sea (illustrated by Patrick Benson) Walker, 1987, all by Adrian Mitchell.
The Baron Munchhausen series books belong to my father (and other people in the world), but still I like them. The Baron Munchhausen travels around the world, doing all these crazy things. Once his friend Robin said, "You can't go down Mount Etna in less than one hour. " So the Baron went on to Mount Etna, and went down probably in an hour, but it took him a couple of months to get back to where he was staying, because he was swallowed up by a ginormous fish, bigger than the whales, and there were loads of other ships. And that's just one of his adventures. You can read them in these three books, but I'm sure there are a lot more stories about him. I'm writing one called "The Baron Chills Out."
I really really like these books, because of all the whacky things that don't really happen. If you do not believe the Baron, he'll challenge you to a duel to the death on the 31st of February at the west gates to the Garden of Eden. I recommend these books for ages 7 to 99. Young readers can read with a parent, better readers can read alone. More superb illustrations by Patrick Benson; see HOB.
