Supplement from the Argentine magazine Lúpin (1966 to 2007), created by Guillermo Guerrero and Héctor Sídoli. This 65-page document is dedicated to kite building and includes clear plans and step-by-step instructions. Designed so children could build and fly their own kites, the supplement combines play, learning, and creativity. It is a small but remarkable example of hands-on educational publishing and a true gem for kite enthusiasts.
