A phalanx of heads stands like ancestral guardians reminiscent of the moai megaliths of Easter Islands, although the Topeng Series was inspired by Yusof Ghani's group trip with students to Sarawak where he was fascinated by the rituals of the Dayak masks (hudoq) of the Kayan and the Kenyah, of which the intrinsic value is to protect against evil spirits. They get an emotive and symbolic quality when rendered as grimaces concealing real intentions. Yusof Ghani had even shown his Topeng at the Takashimaya Gallery in Singapore, and at the Jenkins Johnson Gallery in San Francisco in 1997.
