Minimôme - Découvre l’Alphabet ☜

Written, designed, and illustrated by Gérard Gibo. Published in France by JC Lattès in 1974. Large 3D letters provide a simple but brilliant idea for exploring the alphabet. As far as I can tell, 'Minomôme' is the small character who navigates these pages, and it appears there is a series of books starring this Ziggy-like figure.
