I once had the privilege of going through the store rooms of the Museum of Ethnography in Budapest to handle all the Lajos Biro collected objects from the Huon Gulf and Astrolabe Bay. I remember going through draws full of Huon Gulf neckrests of all shapes and styles from the classic single figure, the back to back double figures, the unusual abstract versions and remember at least one of the present type. My example is ancient, collected in 1905/6 by Gottfried Schmidt and has an additional 50-60 years of field use prior to that date. The piece is 6 5/8” (16.7 cm) in height, dates to the mid 19th century and sells for $7500. Questions?
