Hi there… I’m writing to inquire about your circular I Ching graphic called i-ching-by-daylight. Is this an original graphic you have created or did you find it somewhere else? If it’s original we’d like to ask permission to use it in a book being self-published soon. It would be a background watermark type of image on the title page of each chapter. Please let me know at your earliest convenience if it is original or there is another copyright holder you know of, and if you’re open to granting permission of use if it’s yours. Thanks, Marshall
