A memorial portrait of Joseph F. Lizzadro, Sr. was commissioned in 1972. It contains more than 1,300 pieces of natural stone, precisely cut to fit together without the use of grout. Created by Bruno Lastrucci of Florence, Italy, the technique is called “commesso di pietra dura” (the joining together of hard stone). This art form has been practiced in Florence, Italy for hundreds of years.

The Museum is fortunate to have several examples of Florentine mosaics.
