Chaveiro Dragon Yin Yang

The original yin-yang image is from a collection of clip art I purchased years ago (Borderbund) and looks to have been originally a plate. I have seen it used elsewhere, but it is "Artist Unknown" as far as I have found. PLEASE let me know if you have the info (I would love a set of dishes with the original image if they are available!) I enlarged the image, cleaned up the edges and details, then used it as a base for a wide variety of png images. I then placed them on the products, with and without accent images I created.
