This is a mixed media painting on superior acid free 140 lb. watercolor paper. I use only professional artist grade materials as archival quality is very important to me. All pigment are lightfast and permanent. The color of the photos may look slightly different than the real life colors as all monitor settings are different. If this work is matted in an acid free matt this piece should last hundreds of years. I have used Sennelier interference oil pastels in this piece and they just dont show up in photographs as they appear in real life.This work is an original painting and not a print.
