Dibujo en boceto

 A top-down studio photograph, precisely centered, of a single large sheet of técnico drawing paper with a subtle grid. The paper is isolated on a uniform light grey background. At the very top, in hand-lettered technical script, is the text: 'FIGURA 1: SISTEMA DE FUENTE GEOMÉTRICA INKZY - PLANO DE CONSTRUCCIÓN GENERAL'. Below, the complete modular construction of the A-Z alphabet and numbers 0-9 are drawn with extreme precision on the base blue grid. All lines (blue construction, green symmetry, red measurements) are sharp. Each letter and number has extensive handwritten annotations and dimensions (e.g., 'R=...', 'cotas de ángulo' like 45°, 90°, 'cotas de dimensión') in their respective colors. Callout circles (1-17) are positioned precisely, pointing to specific features. In the upper right are three detailed boxes: Detail A on the 'A' with 'DETALLE A: CONSTRUCCIÓN DE A', Detail B on the 'Q' with 'DETALLE B: CONSTRUCCIÓN DE Q', and Detail C on the numbers/symbols with 'DETALLE C: DETALLE DE NÚMEROS Y SÍMBOLOS', each with its specific callouts. In the lower left, the complete multi-colored legend text is verbatim: '1 CUADRÍCULA MODULAR BASE...', through '8 TANGENCIA CRÍTICA,' with all color codes intact. In the lower right, the entire INEZY title block is present and filled with verbatim text: 'INEZY: ESTUDIO DE TIPOGRAFÍA GEOMÉTRICA 'INKZY-MOD 1'', 'REF. INKZY-01', 'PLANO DE CONSTRUCCIÓN GENERAL (FIG. 1.1)', 'DIBUJADO POR: A. CALVO', 'FECHA: 15 NOV 1970', 'REVISIÓN: A', with the color key filled out. The drawing has a clean, technical draft style, not digital, with authentic pen work.
