Look closely and you will see some handwriting on the puzzle. The two vertical lines near the woman's head say:
Valentine Greetings
This Valentine greeting I send to you
Because my love it breaks anew
And spreads its ecstasy; its part of life
When I think of you my darling wife

 How could you not like a Valentine's gift like this? There were two others with this, another for his wife and one for a daughter, each with a handwritten poem.
