The poster plays with the Latin notion of “margin”, as a leitmotif, in a dynamic symbolic alternating game between the central and the marginal. The use of drawing of the city bell tower of St. Domnius by Marko Marulic on one of the margins of a medieval publication points to the consequent marginality of events but defiantly positioning itself together with the book's margin in the center of the poster. The epic "Judith" is moved to the margins (lat. “in margine”) of the poster because it is marginal in relation to the celebration of Sudamja. The new composition is bordered (lat. “marginata”) by a frame - a margin, and St. Domnius and the epic "Judith" thus together become the new central, significant.
By the same method of the inherited book system, but in a modern style, on a new margin, the idea of the poster is explained, and the written and drawn typographic heritage is pointed out.
Yellow and red are the traditional colors of the festival "Sudamja". On the poster, the original initials MM are included in the name of the celebration "Sudamja" and the Roman mark for the number 500.
