This week, we welcome to our list the renowned German art and photography book publisher STEIDL, founded more than forty years ago and still led by the visionary publisher, printer and friend to artists, Gerhard Steidl. Releasing today are dozens of influential, provocative and even seminal titles that no serious collection can exist without; releasing over the next few weeks are many dozens more. Below is a selection of images from the current and forthcoming STEIDL list.
