12 Absurd Facts About ‘Alice in Wonderland’
11. ALICE’S ADVENTURES IN WONDERLAND WAS A PIONEER OF BRAND LICENSING.
Carroll was a savvy marketer of his story and characters. That’s perhaps the main reason the story is so well known today, even for those who haven’t actually read the book. “He’s one of the first authors working with manufacturers to bring out related products,” Vega says. He was all about the tie-ins. He designed a postage stamp case decorated with images of Alice and allowed her image to adorn cookie tins and other products. For readers eager to learn more about the origins of the book, he produced a facsimile of the original manuscript, a rare move for an author of his day. Later, he created a shorter version of the book for even younger readers. His 19th century business savvy foretold franchise-obsessed companies like Disney decades before their founding.
I've known of Alice for as long as I can remember. Never read the book though. My wife got it on the Kindle to read to the kids. She didn't read it to them. Lewis Carroll must have been on an acid trip. That was one weird book, and nothing at all like most of the movies/tv shows produced about it.
