Overhead projectors and then tablets have replaced them over the decades, but the collective memory keeps in mind the image of the teacher in a grey apron, perched on his platform, a wooden stick pointed at these school posters\. Depicting scenes of life, animal or plant biology plates or reporting on a job, these panels from the 50s allowed to illustrate lessons to children, before the arrival of school textbooks. Today, there is no question of surprise glue or elocution lessons, we will simply enjoy the sweetness of the images, the sparkling colors and the nostalgia of an era\. and sometimes its comicality too! The themes of this educational poster and recto-verso are: " The breeding farm - The Dairy ". The posters are made of thick cardboard. The colors are still very nice and the drawings very original. The condition is good, slight tears may mark the posters but no losses. A different illustration is present on the front and back. Themes " The Breeding Farm - The Dairy " 76cm long, 56cm wide.
