World's Most Expensive

I came across the photograph that is apparently the most expensive ever sold.  Stop looking at this blog now and Google.........." Rhein II"........ by Gursky.  Study it carefully.  It's complicated.  I showed it to my wife (being an artist) and asked her to explain it's  $4.3 million value to me.  " Simplicity, power, artist vision" she tried to bullshit.  An art world with too much to invest and not much taste seems like a more realistic evaluation.  It reminds me of the now famous painting of "Cow Eating Grass".  Explaining questions about the blank canvas, the artist answers:  Where is the grass? Cow ate it.  Where is the cow?  Why should she hang around when there is no grass to eat.   I would like to offer any of the following photos for sale at the reduced price of only $3.3 million.  OBO.
