A plentiful graphic repertoire of geometric and linear engravings, with repeated combined patterns which can also regard both faces. Isolated bundles of parallel lines are predominant, followed by polidirectional bundles of orthogonal lines which comprise complex graphemes. The striped pattern is present in different variations. There are short linear sections, in series or in groups engraved along the edges of the support, and unorganized linear signs dispersed on the surfaces.
