When we saw Portland-based designer and art director Mengyu Chen’s paper pop-up books on Booooooom, we instantly fell in love. The minimal design and simplicity of action recalled our childhood, when craftily constructed stories sprung to life. It was a magical first encounter with animation and one we can happily relive until we’re old and gray. Lucky for us, playful pop-ups are being marketed for adult readers more frequently, and we’ve chosen a few incredibly designed books to share with you past the break. Some can be purchased and others simply admired — the handiwork of artists who similarly view the 3D books with childlike wonder. See more amazing pop-ups below.
