The goal of the article is to evoke the figure of Mauricio Amster (1907-1980), a Polish graphic designer, typographer, book designer, magazine and poster designer, born in Lviv, educated at a design school in Berlin, who, active in Spain and especially in Chile, established the foundations of modern book culture in both countries. The article proposes to explore Amster's work through the concept of "shifter," examining how his "book-objects" function as symbolic and indexical signs that combine autonomous art and mass production, and how these elements intertwine within the context of post-vanguardism and the society of the era.

The quatrefoil motif, a widespread symbol in ancient Mesoamerica, is associated with caves and serves as a portal to the supernatural world, enabling communication with gods and ancestors. This article investigates the undeciphered Maya logogram T510cd, commonly referred to as the quatrefoil glyph due to its distinctive shape. Through a comprehensive analysis of inscriptions featuring T510cd, complemented by selected iconographic, archaeological, and ethnographic investigations, this article sheds new light on previous attempts to decipher the quatrefoil glyph. The study reveals that logogram T510cd likely represents the Maya word "ch’en," signifying openings or holes in the earth, often indirectly related to pools and caves.

The aim of the current paper is to investigate of the role of the children in prehispanic society from the perspective of human remains from the site of San Francisco (Yauca Valley) on the southern Peru coast dating to the Late Intermediate Period (900-1476 AC). The bioarchaeological analysis of the quality of bundle textiles, health condition, body position, the artificial head modification, and mummification techniques were used to establish if the subadults received a different treatment related to their social origins or age. A radiographic and anthropological examination was conducted to investigate 22 wrapped mummies. The result show three different types of artificial cranial modification, as well as trace of artificial mummification practices. The children (including infants) participated in the same funerary treatment as adults. The results suggest an identification with the group started at the moment of birth. The diversity of the youngest children showed a complex social structure in which social status was inherited from the parents.
