"His master's breath," a souvenir of Beaumont, Texas.  (Here's another vintage "His Master's Breath."  We also previously encountered an ancient mosiac precursor to the dog Nipper of "His master's voice" fame.  And there's this vintage photo of another listening canine.)

What do "fifty shades of grey" have to do with the Wizard of Oz?  One might think that in the Oz spectrum, ruby (slipper) is connected to emerald (city) by yellow (brick road).  However, there are actually fifty shades of grey between ruby and emerald.  (Spoiler: it's the fifty shades of Toto's coat of many colors.)

You've heard of "His Master's Voice," but "His Master's Breath" smells like whiskey.  Date uncertain.

Here's a precursor to the photographic phenomenon of dogs with iPods.  The vintage illustration is captioned "Pavlov's artificial neurosis."  From Biology and Man by Benjamin Gruenberg, 1944.  The photograph is courtesy of Nao-cha.
