Acrylic on canvas 20 x 20 cm, buying original abstract painting

This is an original acrylic painting on stretched canvas. Size: 20 x 20 cm and 1.5 mm deep. Because of my graphic background, composition and use of color are very interesting for me. In combination with the fine lines and buying small pen drawings, this gives an exciting picture. I have enclosed a certificate of authenticity, with photo, date, name and my signature of the artwork. Ready to ship, and ready to hang (Colors may differ slightly from the original due to light and camera settings. No filters were used when shooting and the photos were not post-processed.)
