MONT SAINT MICHEL / "Groupement National de la Baie du Mont-Saint-Michel": Rare 1927 "part de fondateur au porteur" share of this company, which wanted to develop the Tombelaine islet in the Bay (a few km north of the Mont) as a tourist resort. The company was never able to buy the islet, which was pre-empted by the State and classified (it is now a nature reserve that is off-limits to visitors); the company went bankrupt in 1933 - beautiful illustrations (32 x 41 cm)
