I should check if "Doari Majumdar Maity" is a real person. Maybe a quick search would help. If it's a fictional character or a work of art, the approach would be different. Alternatively, "Doari" could be a term in a specific language, like Bengali, given the last name Maity. In Bengali, "doari" could refer to something like a traditional craft or art form, such as doari embroidery. That might be a possibility. If that's the case, the PDF could be a research paper or an article discussing this craft by someone named Majumdar and Maity.
