Framed in a sturdy hard wood, it is marked "MADE IN PORTUGAL".

The double-sided slate surface bears subtle surface scratching from use typical for a slate of this age. The curving vertical line seen in the first photo is the result of light reflection and is not an actual imperfection. The back side of the slate has been incised with vertical and horizontal lines for mathematical work.

This diminutive slate retains the rich patina of its 100+ years of age and can be displayed vertically or horizontally.

A sweet addition to one's school memorabilia collection!
