Very popular in 1920s, metamorphic images like this were created mostly in France. Depending on your focus, you might see a skeleton's skull, or, indeed, a lovely clown couple sharing champagne. The gentleman appears to plead with his beloved for some special favors.
These pictures are still as engaging as they were when initially issued as the design is so clever and the execution is superb! And now you can feature one on your fridge!
