Ex Philadelphia Academy of Natural Sciences, almost certainly from the type find in the 1930s which was named after mineralogist Mark Bandy. Old fashioned wood display label from somebody's display collection , included. This is a MAJOR example of the species with a bit of 3-dimensionality to it, though it is seemingly innocuous in the photos, for the size and richness of the specimen. SIGNIFICANTLY, this specimen does NOT SHOW ALTERATION to eriochalcite, as is common on some specimens and reduces value of even many museum pieces thought to be bandylite (which aren't).
