Oil on canvas. This 24" x 36" piece was a blast to create. I love working with straight lines. As you may know, working with oil can be very messy, and this piece sure was. It was a complicated piece to assemble and disassemble because each of the numbered pieces had to be taken off in reverse. It was laid out on glass and then transferred to canvas. Photographed, it has the illusion of a pyramid. My asking price is $750 plus shipping. I am taking bids.
