First of the two preparatory drawings for the print Two groups of bullfighters being run over at once by a single bull.  The present preparatory study, which focuses exclusively on the central group of the future print, is characterised by its great precision and detail. In it we see the bull charging a horse with the picador on top of it, who is thrusting his pike into the bull's neck. Between the two contenders, contrasting in their posture and lighting - the horse receives more light than the bull - a fierce fight is taking place. Behind the two fighting animals we can see a series of figures, probably labourers, who are trying to separate the bull from the horse, as the bull has a piton stuck in the equine's belly. In the corner on the left, in the foreground, another picador's horse is lying on the ground with its guts spilled after a previous attack by the bull. In the background, the barrier is indicated in summary form, unlike what Goya would do in the second preparatory drawing and in the definitive engraving.

On the back of the sheet there is a slight hint of a horse in sanguine and traces of sanguine in contact with other drawings.
