An open, hard-back book with blue cover.
In the Apple artwork for this emoji, the book is open to a page with the following text:
Here’s to the crazy ones. The misfits. The rebels. The troublemakers. The round pegs in the square holes.
The ones who see things differently. They’re not fond of rules. And they have no respect for the status quo. You can quote them, disagree with them, glorify or vilify them.
About the only thing you can’t do is
From “The Crazy Ones” text as part of Apple’s Think Different Advertising campaign of the late 1990s to early 2000s.
Open Book was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
