It is common to find instant portraits done on the spot at Chitra Santhe, or any art fest. In fact, there was a computerized stall in front of The Bombay Store on M.G. Road. I really don't know how that worked. But, i guess it profited. I don't remember this properly, but they were signed Van Gogh.
I was surprised at this, but then realized that these were quite popular. Van Gogh and this. What comparison!!
