This sample card is not on exhibit, but just published in the catalogue. I saw it in the collection of Corning Museum of Glass last year. It seems from Sick of Amsterdam; it has three notes at its margins, written with a pencil:Kumasi, 12.10.1935; Amsterdam 31.10.1935; Venedig 15.4.1936. The five beads are Ashante powder glass beads: it looks as they were sent to Venice to be copied.
