The painting has a layer of fluorescent paint which is black light sensitive as well as glows in the dark. The pictures show each view in the different lighting options. This is part of the "Moon Series" which has a total of 6 paintings in it. There is a little difference on this painting as I have added a patriotic theme to viking ships which are passing while on their journeys. I love the Viking culture and enjoy painting various symbolic themes using the Viking Ships as well as the ravens. The size of this painting is 18x24 inches with acrylic paint on gallery wrapped canvas.
