Just a really neat label with a dyscrasite that is notably crystallized but admittedly lumpy. Still, its hard to get rich specimens of this material from Andreasberg. this certainly dates to the early 1800s or even earlier back. And, I think the price is right for a good representative specimen of this rarity, with a nice old label from the catholic community school of Lazazist Brotherhood College in Lyons, France 2.7 x 2.6 x 1.9 cm
