Paolo Soleri ceramic 1990's discount clay bowl from Cosanti

This bowl was made at Cosanti discount in Scottsdale Arizona in the late 1990's. It is about 4 1/2" wide by 3" tall and 1/8" thick. It is authenticated by the signature on the side. I don't the name of the artist who made the bowl. The condition is flawless. It is raw and natural.
