Beoher Rammanohar Sinha's legible short-signature in Devanagari-script as Ram on the Preamble-page (lower-right corner within the outermost border-design), and as rammanohar on other pages of the Constitution bear unambiguous testimony to this fact. He was the favorite disciple of Nandalal Bose. After finishing the Constitution, some leftover art-material was carefully preserved by the artist which he bequeathed to his son Beohar Dr Anupam Sinha.
