I went to the Soloviev Foundation for a private viewing of someones art collection. It was amazing. Large Matisse dancers, Giacometti's portraits, Picasso. This real-estate fellow collected some significant works of art. One piece that impressed me was a "portrait" done by Paul Klee. Not very familiar with his work I was enamored with a simple painting. Minimalist, blocks of color separated by lines that define the face. I could not take a photo of the piece, but I searched a little and found something similar.

This inspired the pendant and pin version of the portrait. 

Pendant is simple and hung on a delicate chain that you can actually remove and wear on its own. Chain is 36" long.

Pendant is 2.5"x1.5" and very light.
