The painting depicts a student, recognizable by his cap, the Cerevis, who uses a thread to lower a sealed love letter to the open window of the apartment under his room.

In the lower window, viewers can see a young woman so busy with her handwork that she does not notice the letter.

Another woman, probably her aunt or governess, notices the letter and opens her mouth in astonishment.

The sand-colored facade is richly structured, oblique shadows show that the scene takes place in a town with narrow streets.

Spitzweg also added small details to the picture: a bird cage, the Phoenix Insurance Shield and a couple of pigeons, in an ironic metaphor for the two youngsters.
