Isaac Salazar has created a series of “Book Origami” to create some interesting type pieces.
“I see my work as a way to display a meaningful piece of art onto a book that would otherwise sit on a shelf and collect dust; it’s also my way of recycling a book that might otherwise end up in a landfill. The words or symbols I use are drawn from anything that invokes inspiration or encouragement, such as “Read”, “Dream” and the Recycle symbol. If my work also makes people look at a book and even art in a new light then the piece has done its job“
