Monotypes are oils that are painted on glass and then transferred to paper. Sometimes it's only possible to make one print from the painting and other times there is a second one that's called a "ghost". Rarely a third one would be "ghost 11". Everyone is different.
All Original. My watercolors are done in many different ways. Some are on location and some life poses, others from sketchbooks. I rarely use a photo and if I do it's for a reminder with the painting have little resemblence. All are matted.
