 In 1943 , Ray started work at D.J. Keymer , a British @-@ run advertising agency , as a " junior <unk> , " earning eighty rupees a month . Although he liked visual design ( graphic design ) and he was mostly treated well , there was tension between the British and Indian employees of the firm . The British were better paid , and Ray felt that " the clients were generally stupid . " Later , Ray also worked for Signet Press , a new publishing house started by D. K. Gupta . Gupta asked Ray to create cover designs for books to be published by Signet Press and gave him complete artistic freedom . Ray designed covers for many books , including <unk> Das 's <unk> Sen , and <unk> Bangla , Bibhutibhushan Bandyopadhyay 's Chander Pahar , Jim Corbett 's <unk> of Kumaon , and Jawaharlal Nehru 's Discovery of India . He worked on a children 's version of Pather Panchali , a classic Bengali novel by Bibhutibhushan Bandyopadhyay , renamed as Aam <unk> <unk> ( The mango @-@ seed whistle ) . Designing the cover and illustrating the book , Ray was deeply influenced by the work . He used it as the subject of his first film , and featured his illustrations as shots in his ground @-@ breaking film .
