Riccardo Rinaldi was an artist for Rolf Kauka's comics production from 1963 until 1974, and sporadically in the 1980s. Educated in art, Rinaldi began his career working for several Italian advertising agencies. He then joined Kauka's comics team in Mailand, Germany, where he became the main artist of 'Die Pichelsteiner' in Lupo Modern and Primo, a series he created in 1966. He has also illustrated stories with 'Fritze Blitz und Dunnerkiel' (later renamed to 'Siggi und Babarras').
For Fix und Foxi Magazin he additionally did stories with the 'Fix und Foxi' family, as well as 'Diabolino', 'Tom und Klein-Biber' and cover illustrations. From the mid-1970s, Rinaldi worked mainly in advertising. He drew among others for Storck chewing-gum, and created the character 'Heido' for Heide-Park Soltau, of which also several comic albums appeared. Other creations during this period were 'Das Streichquartett' and 'Harrycats'. In the 1980s, he briefly returned to Kauka with new 'Pichelsteiner' and 'Fix und Foxi' stories.
