For me, this entire matter has more holes than the plastic colender Mrs. Mulligan uses to wash chicken necks in.
For one suspicious hole, a Copyright search reveals that the work was taken in 2002 but never registered until March of 2013. Additionally, near as I can tell, it is the ONLY work by this particular photographer that's been registered. Ever.
Here's the complete listing from the copyright office's search function:
