"Drawing is the language that enables the men of the Ice Age, in the caves at Altamira in Spain and Lascaux in France, to speak to us, today, and to the men of the hundreth century, with perfect clarity. Drawing is the universal language. Draughstmen communicate instantly and effectively with anyone, anywhere in any time."
An inspiring quote from the book "Complete Guide to Watercolor Painting" by Edgar A. Whitney. I'll definitely post more about this great book in the future. The images are from the Lascaux caves in France.
