Having graduated from a secondary school of electrical engineering, Jiří Grbavčic worked his way through several jobs. Since 1990, he has pursued the career of artist and illustrator to the exception of all others. He has illustrated comics with adventure story themes. He has provided illustrations for book covers, short stories and other forms of writing published in books and magazines addressing various subjects. He is the artist of dozens of covers in the Divoký západ [Wild West] novel series. His trademark methods are pencil drawing, pen-and-ink drawing, combined watercolour and oil painting. His work is characterized by careful drawing, a smooth painting technique and depiction of reality that is almost photographic in effect. His work includes portraits, the capturing of the historical monuments of his home town and subject matter related to wine-making.
