Yeah, I saw the picture in the book, however the date of the photograph made it somewhat unclear regarding whether it had been made before stiechen's. I find it kind of amazing these famous photos were done before. I wonder whether the artists saw the photos before hand and copied them (I find that doubtful) or if they simply had the same idea as someone else. If the latter is correct, it really makes me doubt the conception of artists (and their art) as unique. Thanks for your input.
