Old real school slate with cooked rubber frame?

Old real school slate with cooked rubber frame?

It is difficult to date this school slate but it most certainly predates the 1960s.

This is a real slate.

The grid on one side of the slate is faded.

There is a crack in the slate but it remains solid, see the photo.

You can see a few tiny droplets of hardened white paint.

The frame appears to have been made of rubber and it would have hardened and cracked over time.

Unusual school slate model.

Length: approximately 26.5 cm.

Height: approximately 18.3 cm.

Used item.

This school slate has been around for at least 60 years and is by no means in new condition. It must therefore be taken into account that despite a rigorous selection and description in order to present a quality set, it may contain minimal defects caused by the passage of time in addition to those indicated in the description. To have an impeccable condition, I invite you to turn to new or more modern objects.
