Many of these paintings are designated as "the work of Master Muhammad Siyah Qalam (i. e. the Black Pen)". The insensitive manner in which these inscriptions are affixed, often even upside down, as well as the inclusion of title and nickname, make it obvious that these are only attributions by an unknown person or persons; the reason for the name itself remains unknown, as in spite of the reference to black-and-white drawings implied by the words "Black Pen", the work assigned to the artist consists almost entirely of coloured paintings.
