This illustration said to be made by Satyajit Ray is 90% fake and definitely not an original. I have the exact replica set of papers with signatures, pictorgrams drawn purportedly from Ivan Lendl, Marlon Brando and other famous people. In fact I recall buying it as a booklet in a curio store in India
Have your own photo?
For what it's worth, the line work of the posted sketch seems to match the quality of other sketches by Satyajit Ray's hand.
