Manual Steiger. Introducción á la enseñanza práctica del sistema de kindergarten--jardines de niños--segun el fundador Federico Fröbel y su discípula Mme. María Kraus-Blte
A Spanish-language kindergarten teaching manual issued by E. Steiger & Co. in New York in 1900, adapting Friedrich Fröbel's method and Maria Kraus-Boelté's teaching for Latin American and Spanish-speaking instructors. Numbered line diagrams show tablets, sticks and folded paper arranged into triangles, rosettes and octagons, with hatched shading marking wood grain — a source of modular geometric motifs and figure-numbering layouts.
