He enrolled at the Academy of Fine Arts in Zagreb, subsequently pursuing a career as an illustrator and comic book creator for local publications.

He left the Academy of Fine Arts during his first academic year to focus on his professional work of creating illustrations, caricatures, posters and graphic design.

He based his illustrations on literary models such as Alex Tolstoy, Zane Grey, August Šenoa, Jack London, B. Traven, Max Brand, and H. G.

He is not a typical Western hero, as Maurović sought inspiration from his daily acquaintances, basing Stari Mačak on a construction worker he frequently met at a pub on Ilica street.

This was quickly followed by Sablast Zelenih Močvara (Spook of the Green Swamps), where Stari Mačak was joined by wandering poet Polagana Smrt (Slow Death) along with his parrot Penelope and his horse Tulip.

Benson described him as a superb master of the art of cartoon, stating that "intensified interest in mass communications have resulted in reconsideration of his entire oeuvre".
