I had this piece authenticated by Paolo himself, and it includes copies of the original sale record from 1969 and a signed certificate of authenticity. It is made of aluminum and forged in the lost styrofoam process, as were most of his one-of-a-kind works.
It is signed as seen in the picture with "Cosanti PS" as were his other early works. It is also marked 68-6, which indicates it was his 6th work of 1968. This item is in the category "Collectibles\Decorative Collectibles\Bells".The seller is "drsyszgyesq" and is located in this country: US. This item can be shipped to United States.
