I asked Google AI if there are Easter eggs put in by editors and printers and got this reply (I copied and pasted it exactly as Google AI gave it to me):
Yes, Easter eggs are frequently placed in books and documents by editors, designers, and printers. While famously common in video games and software, the long history of publishing is filled with hidden messages, inside jokes, and typographic quirks left by the people who put books and media together. [1, 2, 3]How Editors and Authors Hide Messages
- Acrostics and Ciphers: Authors and their editors have a long tradition of embedding hidden words. Lewis Carroll embedded an acrostic poem at the end of Through the Looking-Glass that spells out "Alice Pleasance Liddell," the real-life inspiration for Alice in Wonderland. [1]
- Editorial Grudges: In the pulp fiction world, one author retaliated against an editor who constantly misspelled a character name ("Fredo" instead of "Frodo") by explicitly writing "Frodo Baggins" as a random, awkward bystander in the story. [1]
- Typographical Quirks: In the digital age, Columbia University researchers even developed "FontCode," a method that allows designers to alter the shape of letters imperceptibly, effectively hiding secret messages or copyright information inside ordinary paragraphs. [1]
The Secret World of Printers
- Printers' Marks: In the early days of the printing press, compositors and printers often hid tiny caricatures of themselves, initials, or playful crests within their traditional printers' marks. [1]
- The Devil’s Tail: The manual lever used by historic pressmen to press paper to type was known as the "devil's tail." Many printers embraced this folklore and playfully inked hidden "typographical devils" or unassociated images in the margins of heavily printed books. [1]
- Tracking Dots: While not a whimsical Easter egg, most modern color laser printers print nearly invisible microscopic yellow dots onto every page. These function as a government-mandated security mark that identifies the specific printer's serial number and the date and time of the printout. [1, 2, 3, 4, 5]

Two days ago, I read the LIFE commemorative issue printed in 2025 about The Sound of Music. It's called "The Sound of Music: 60 Years Later, the Hills are Still Alive." The magazine reiterated that one of the truly accurate things about the Broadway musical and the Julie Andrews movie is that the real Captain Baron von Trapp refused to fly the Nazi flag.
Page 18 of the book has a really obvious, unusual typo. I'll give you the page first and let you look for it (I did edit the photo a little so that it didn't get tagged as having offensive images, but I did nothing to the text):
Did you see it? Here's a photo of the part with the extra printer mark:
Isn't that cute? It's a little flag waving on the letter "i" in Vienna! The Austrian flag is two horizontal red stripes with a white stripe running between, so I think this is meant to be the Austrian flag, rendered in black and white just like the old photo directly above it.
My grandfather was actually interned by the US government during World War II as a suspected Nazi, but my family, as far as I know, has always been loyal to the USA and not in sympathy with persecution of minorities (although there is that one uncle....we all have black sheep in our families.)
