Antique Pre-Columbian Chimu Inca Blackware Ceramic Figural Whistling Vessel

Antique, pre-Columbian, Chimu, Inca blackware ceramic, bridge-spouted, double-chambered figural, musical whistling vessel, circa 1100-1400 AD.  The front lobe depicts a seated man (lord or shaman) holding his hands on his lap, wearing a long tunic and hat, connected by a bridge handle to a tubular spout. 
The second bridge connects the man's body with a cherimoya fruit of a rounded, compressed form decorated overall with tufts.
A whistling vessel makes a bird-like chirping sound by blowing into the spout or by pouring liquid from one chamber to another.
