This book is well described by its title. These are truly photographs that test the limits. The book is 63 pages long and contains many very unusual as well as creative sexual photographs. All are in black and white and all are calculated to surprise. The front wrap of this quarto size volume has a crease to it but lies flat as intended. There is an introduction written by the photographer Michael A. Rosen and an afterword by David Steinberg. A very unusual offering and for sale to adults only.
