as a former publisher and founder of a press (Lumen Edtions), I published Ralph's work on many of my book covers (in fact, when i had my own book published - not by me, duh, but another press, it was an image by Ralph Gibson that was used on the cover.) His work is simply amazing. If you don't know it, Google his name and check it out. His clean lines and simple shots make him a classic. His nudes are tasteful, beautiful and erotic all at once.
