This illustration of the yellow submarine makes me smile. I have loved The Beatles ever since I was a little girl so anything that I can illustrate to represent them, I'm all for it! This drawing was created with watercolor pencils and outlined with pen on 140lb. cold press watercolor paper. 
This drawing comes with an overall dimension of a 8"x10" white mat with an opening of 4.5"x6.5" and a foamboard backing.
