Paul Calle is an amazing artist, and has had his illustrations published by numerous magazines (Ladies' Home Journal, Readers' Digest, Redbook) as well as books, a series stamps for the U.S. Postal Service, and a book of NASA-commissioned sketches documenting the history of the Apollo space program. Mostly Mr Calle sticks to very simple tools: a fine pencil, a broad pencil, and eraser, and paper- usually newsprint. This one used a few specialty pencils to get the super-dark areas that almost look like they are pen-and-ink. I encourage you to get the book, where this image is much larger, and you can appreciate all the fine detail and dramatic lighting.What is most remarkable about this book is that every single illustration is done with nothing more than pencil on paper. Calle shows the diversity of effects that can be achieved with such simple tools.. it really has to be seen to be believed. If you can get your hands on this book, check out pages 61 and 152 in particular. This is photorealism, with nothing but a simple pencil.ARE YOU HEARING WHAT I'M TELLING YOU???? THESE PICTURES ARE ALL JUST A SIMPLE PENCIL AND A SHEET OF NEWSPRINT, FOLKS!
