There Just Can't Be Too Many Bob Portraits

Another great portrait by Hurrell of the young Mr. Montgomery.  And a very nicely done postcard. 

And a very similar photograph from a magazine.  Hmm ... if Bob tried a hairstyle with a part, it was always on the left side.  This photo shows it on the right side.  Something wrong here.  

Voila!  I flipped the image to find it's the same photograph used on the postcard!  I'd imagine Hurrell was not pleased.
