The image is a black and white illustration of a group of people dancing on a street corner. The title of the book, "Una Noche de Garufa" by Eduardo Arolas, is written in large, bold letters at the top of the image. Below the title, there is a subtitle in Spanish that translates to "The Night of Garufas" in English.

The illustration shows a group in a dance pose, with one person in the center holding a microphone and another holding a guitar. They are all wearing suits and hats, and some are dancing with their arms and legs in the air. The background shows a street lamp and a building with a sign that reads "Tango Piano."

There are also several other people in the illustration, including a man in a suit and a woman in a dress, who appear to be dancing. The illustration is done in a cartoon-like style, with exaggerated features and exaggerated facial expressions. The overall mood of the illustration is lively and energetic.
