Thank you, Mashable, for this:
In 1908, author and artist Peter Newell published The Hole Book, a fancifully illustrated children’s tale that incorporates a literal hole in the pages to trace the trajectory of an accidentally-fired bullet.
The errant projectile sows chaos through a variety of scenes, shattering fishbowls, perforating hats and detonating gas tanks before coming to rest in a particularly dense cake.
Newell had previously built a career on his humorous drawings and poems in outlets such as Harper’s Bazaar and the Saturday Evening Post.
In addition to The Hole Book, he published other conceptually playful children’s books, including a compendium of pictures and poems that could be viewed upside-down or right-side-up, and a rhomboid-shaped volume, The Slant Book, that traces a rogue baby carriage’s topsy-turvy descent down a hill.
The link contains full facsimile images of the book’s verses and illustrations.
Well worth your time!
