I created this piece on 3/4 inch hardboard. Created by added layers of acrylic paint and texture. THis painting has such gorgeous layers. I added a bit of pastels and conte to help areas of this painting stand out. PLEASE NOTE: THE LUMBER YARD HAD SOME TROUBLE WITH CUTTING SQUARES TODAY lol !!! It's very close to 24x24 but not exactly square. I will paint the sides to whatever you'd like, so there is no need for framing. It is signed, dated and titled on the back. Ready for hanging simply unpack and hang. International buyers please convo for a shipping quote. Comes with a certificate of authenticity
