Ray demonstrated his visionary prowess in the 70s through his book jackets, skillfully infusing fantastical elements into the ordinary. Exemplary works like "Professor Shonku'r Kandokarkhana" (1970) and "Shabash Professor Shonku" (1974) defy traditional naturalistic illustrations. Departing from rigid realism, these drawings venture into new territories. Shonku's skin rendered in pink or his head depicted with visual transparency exemplify the thrilling and dynamic nature of his adventures. Ray's bold and elaborate artwork pushes the boundaries, captivating readers with the excitement that lies within Shonku's world.
