Stella Kramrisch in her Unknown India: Art from Tribe and Village (Philadelphia Museum of Art, Philadelphia, 1968, p. 78) says,
Kalighat paintings…and brush drawings are monumental in their presentation on an otherwise mostly blank page. Preceding the work of Matisse, some of the brush drawings prefigure it. Out of Indian tradition and impressions of Western painting, the ‘bazaar’ painters, descendants of low-caste and hereditary craftsmen created forms as valid as, and akin to, some of the later work by leading artists in the West.
