A particularity of this tile is interesting and rare. When we get hold of old tiles we look at the back of the tile, the stamp of the manufacture that was imprinted on the back side gives us precise information on the era of production and manufacture.
In this specific case on a sample of 40 tiles we found 14 different brands.
We propose to check the whole game and record all the manufactures present.
Various brands for the same batch of tiles is not so rare.
We explain it with the urgent need for a factory, which, in the face of a sudden, urgent order, is forced to purchase untreated biscuits from other manufactures.
