First verse of this poem is on the front of the card;

Wedding Night

Tall straws, bound tightly.
The Three Stars appear in the eastern sky.
What night is this night?
My love, my love,
At last we are alone!
How shall we celebrate?

Tall straws, bound tightly.
The Three Stars have moved to the southern sky.
What night is this night?
My love, my love,
At last we are alone!
How shall we spend the rest of this night?

Thorn-wood, bound tightly.
The Three Stars have moved to the window’s ledge.
What night is this night?
We are having such a magical time.
My love, my love,
Sweetly we are blessed by heaven.
