Trying to find this miniature from a tiny photo!

I am trying to locate the source of an image that appears on the back dust cover of my copy of The Spirit of Indian Painting (Goswamy):

I couldn't find a credit for this image in the Goswamy text. It is very tiny on the back cover. On a Google reverse image search, only a few rug advertisements came up. I could recreate and work out my design idea from its layout, but I always like to reference my sources. Is anyone familiar with this type of image, and where do you suggest I look to find out more?
