The painting in the picture here is, as I thought, by Ganganendranath Tagore. The style itself gave it away for me. This one is titled, “Millstone of the Caste System”. It is one of his several paintings, which demonize brahmins.

“Purification by Muddy Water”

See the portrayal of Brahmins as physically grotesque.

“Profitable Devotion”

Portraying the Hindu temple, it’s rituals & priesthood in the worst way possible was the legacy of Rabindranath Tagore’s nephew.
