It just occured to me that perhaps the Sick Co. may have literally traded the Krobo either Venetian beads for Krobo made beads, or perhaps batches of glass (in the form of cane, perhaps?) for use in making their powder glass beads. But if that agreement happened, it seems it would have been documented. Interesting! To have sample cards would imply to me an ability to at least place orders with the Krobo.
Giorgio, many thanks for posting about this fine bead show in Milan!
