Freehand drawing workbooks, number 3 and 5 in a series attributed to A. Armbruster, an academy inspector in Belfort, France credited with several other primary education texts in the 1924 "Catalogue général des livres imprimés de la Bibliothèque nationale." We found limited information about him, noted in for organizing "l'exposition scolaire du Haut-Rhin" in 1876, garnered honors at the 1878 Universal Exposition, and enjoyed some success in the Ministry of Education under Jules Ferry. A run of the instruction books was published around 1883, with "Exposition Universelle de 1878, Paris, Medaille d'argent" indicated on the covers. We have found a few surviving copies of that later run, but none of this edition in OCLC, BnF, etc.
