The announcement was made by Binay Tamang, GTA executive member and in-charge of its information and culture affairs department.
An eminent figure in the field of Nepali literature, Indra Bahadur Rai won Sahitya Academy Award in 1977 for his book titled 'Nepali Upanyas Ka Aadhar Haru'.
Among his other works, a short story 'Katputliko Man' and a novel 'Aaja Ramita Cha' have earned him wide appreciation.
