Antique French Modernist Poster The Key to Mental popular Arithmetic - Fantastic Graphic Design RARE

An amazing find!

Gorgeous promotional poster, from a series publicizing the French book, La Clef du Calcul Mental par L. Lamy, L. Lange et A. de Rouget (The Key To Mental Arithmetic by L. Lamy, L. Lange and A. de Rouget).

The math book, a collaborative effort of three Parisian primary school teachers, consisted of tables and exercises and memorization, a rational, simple method of mental arithmetic that was taught to their students with very encouraging results.

After presenting their book to a large assembly of teachers, principles and educational directors from a variety of schools and institutions, popular it was quickly embraced as an ideal textbook for modern primary math instruction.

First published in 1902, I date these typographic posters to 1903, the year that La Semeuse in Paris, France printed the book La Clef du Calcul Mental, which they then promoted with these bright, appealing posters.

Despite their age, the designs are amazing in their modernity. A fine example of great graphic design, it communicates an idea/product with clarity, precision and efficiency.

The poster will look fantastic framed and spectacular as a group. It is especially remarkable that each poster has a unique design, a perfect addition to a collection of typography or numbers.

Each paper poster measures 19.75” x 23” H (50.1.cn X 58.4cm), overall in EXCELLENT condition. Original metal bars have some spots of rust, all posters have even patina, minute foxing, minor ripples which will flatten should you frame or take to a conservator for linen mounting. No odor—from a pet-free non-smoker home.

Although a framed group is shown in PIC#5, this listing is for just ONE UNframed poster (PIC#1).
