This charming artwork features a scholarly brown owl stepping into the role of a wise professor. The character is distinguished by large round spectacles and a dapper navy blue bow tie, giving it an intelligent and friendly appearance. Standing beside a wooden easel chalkboard, the owl holds a piece of white chalk and is depicted in the middle of explaining complex mathematical equations, including integrals and square roots, written in white script. The design combines the texture of fluffy feathers with the classic visual elements of a classroom setting.
