Composition in black and white. Contour lines and shadow areas. Saint John baptizing Jesus and three people watching the scene. On the right of the support, a rectangle-shaped form, in white, corresponding to the door of the dining room wall where the mural would be painted. The figures are outlined. In the center, a figure stading, facing forward and arms wide open. To its left, Saint John standing in profile to the left, holds in his hand a bowl above the head of Jesus. A little further back, to the left, three figures stand, looking toward Jesus and Saint John. The bottom and the floor are geometrized in uneven schematic areas light and dark, suggesting hills.
