Professori Keropää ja jätevakoojat

In this single-issue Finnish comic from 1988, published by Talous ja nuoret NYT, writer Erkki Mäki and artist Ilkka Kumpunen (who also contributed to the writing) introduce the quirky Professor Keropää and his team of "jätevakoojat" (waste spies). A lighthearted educational adventure that uses humor to explore themes of waste management and environmental awareness, it stands as a unique, self-contained snapshot of late-80s Finnish youth comics.
