Share to bearer of 500 francs issued in Paris in 1930.

The headquarters of the Société des Grandes Carrières de Lourdes, former Gaston Blavet company, was initially located in Paris, 8 rue Madame, then 75 rue Saint-Lazare, then transferred to Lourdes, Quartier du Petit-Nice.

It was directed by two women: Mrs Marie Bavard and Mrs Eléanore Lefèbvre (signature on the title) and Mr Pierre Longy (signature on the title).

5,000 shares were issued with a capital of 2,500,000 francs.

There is now a Lourdes Quarries Society (SOCARL). Two quarries exploit the limestone of the Pibeste massif, at the foot of the peak of Alian, on Agos-Vidalos.
