The title "El Prisionero En San Juan de Ulua" means "The Prisoner in San Juan of Ulua". The image is in black with borders around the sides and is double sided. The prisoner of San Juan is a person that Posada depicts several times and he follows his case to when he is arrested to when he is in prison longing to be set free. This is a beginning piece of the series where he is being arrested.
Front: The top of the image has the word "Danza" in the right corner. It is above a picture of a large ship in water next to a smaller boat, which are shooting at a tower in the back left of the picture. Cannons are firing from the tower at the ship and boat in the water. Below this is the title and then two columns of text on either side of a picture. We see a man standing between two soldiers with his arm raised to the side.
Back: The back is split into three columns, the far left being titled "Serafina" and a column of text below. The second column has a picture of a woman in an ornate dress with her hair up and there is text below her. She holds her hand to her collarbone. The right column is all text and in the middle it says "¡Maria! ¡Maria!"
Posada is a Mexican engraver and lithographer best known for his "calaveras", which often assume various costumes, such as the Calavera de la Catrina, the "Calavera of the Female Dandy", which was meant to satirize the life of the upper classes during the reign of Porfirio Díaz. Most of his imagery was meant to make a religious or satirical point. Since his death, however, his images have become associated with the Mexican holiday Día de los Muertos, the "Day of the Dead". He started out making comics for a local Mexican newspaper of Aguascalientes called "El Jicote" ("The Bumblebee"), which was discontinued after one of his comics severely offended a powerful politician.
