Vintage didactic school poster from the 1950s about the anatomy of the arthropods. It is printed on paper and then mounted on canvas. The canvas is then attached between 2 wooden sticks.
 
This school poster was made by Gerhard Gambke (Berlin) and was distributed within Belgium  by Bossaerts & Zoon. The map has signs of wear but is in pretty nice vintage condition.
 
An item that is reminiscent of the school desks and ideal is as wall decoration.
