Ooh the dripping sarcasm of this one! This is a funny twist on the romantic kissing couples found on the cards of the period. When three’s a crowd is exactly it! The standing man doesn’t look too happy. The other gent stole the woman of his heart, and he is kissing her right in front of him.
He’s standing so close to them too. He looks like he’s going to say “EXCUSE ME SIR!” any second now.
This one was posted on October 20, 1918. Most postcards were posted within a year of being published, so this one was made in 1917 at the earliest.
