Last Friday, our publishing class had the great opportunity to Skype with Jynne Dilling Martin of Riverhead Books. We chatted all about the history of Riverhead, the changes that social media has made for the industry, and tips on how to break into the NYC publishing scene.

One thing that particularly stuck with me from Jynne’s talk was how the design team at Riverhead strives to craft a unique “visual identity” for each title. Essentially, this means that if you eliminated the text from each cover, you’d still be able to identify the books based on the graphics alone.(Remember this Buzzfeed quiz on classic book covers?)

So in order to test this, I created a fun collaged scavenger hunt, in which I have tucked 18 of Riverhead’s stunning book covers inside. Some are more subtle than others. Can you find them all? Leave your guesses in the comments below!
