There is one in every room and, although they are few, one can draw comparisons with examples in other caves. for example there is a grill-shaped sign in Gallery B which can be compared with others in the cave of Aguas de Novales and of Marsoulas. In Gallery A there is a rectangular sign comparable to one which is found in one of the recesses at Lascaux. Lastly there is a sign formed by a pentagon and a hexagon side by side which, in the opinion of the specialist Pilar Casado, should be classified as a variant of the oval signs.[17] Tectiform signs: These are without any question the most abundant signs of this cave.
