The full title of this piece is “Soldier’s Goodbye & Bobbie the cat, Sydney”. Before leaving, a soldier says goodbye to his wife while Bobbie the cat admires them from below.
There is no more information, but I like to believe that there is a photo out there that is titled “Soldier’s Reunion & Bobbie the Cat”.
