Iqbal Hussain from Lahore is one of the finest painters we have. Most of his paintings depict women from the Heera Mandi (literally the diamond market)- or the centuries old red-light district. I found the
above image on the Internet today. The news-item referred to Iqbal’s advocacy through his powerful art works:

..Others, who have emerged as spokespersons for the women of Heera Mandi, including leading artist Iqbal Hussain, whose own mother was a sex worker, emphasise their “lack of empowerment, exploitation and helplessness.

His works convey all of these emotions and bring to life extraordinary characters who are often neglected or spurned by the hypocritical culture of Pakistan. (images on the right and below are from here).

Endnote from here:

Being termed a controversial painter in Pakistan, Iqbal’s subjects sometimes tend to shock “puritan painters”, but Iqbal follows his own visions and continues to paint his unconventional and radically innovative paintings. He enjoys a great reputation as an artist in the international art world. His paintings have been requested by Jordanian Princess Wijdan Ali for the Jordanian Gallery of Fine Arts. His were the only ones selected for Unesco Headquarters Prize in 1995, Paris. In 1998, one of his paintings was auctioned at the Sotheby’s Auction House in London.
