The technique I used is: stretched canvases on wooden chassis, acrylic spray and professional acrylic colors.
At the end I covered with a coat of varnish, to protect it agains the UV and dust.
It is ready to hang on the wall.
Dimensions: 50x50X4 cm, 19.7×19.7×1.6 inches.
I signed and dated on the front and I also put my relief signet on the back. I also attache an certificate of authenticity for every piece of art that I sold.
I ship this works in cardboard boxes careful wrapped in bubble foil.
