This pair of fans dates to probably the first half of the 20th century and are from the Solomon Islands. A related example is illustrated in Hutt (1978, p. 68).
The blade of each is made from the aromatic roots of the akkar-wangi plant. The main ribs are from the stripped-back ribs of fine palm fronds. The handles are decorated with bands of yellow and red cotton. The central part of each fan blade has an eyelet of pink woven silk textile which has also been used to cover two of the fine outer ribs.
The fans are in very fine condition, especially given their age.
