In the early 1960s, Yaşar Şilliler was a distributor for Burhan Yayınevi, a low budget publisher of unlicensed comics, including the Turkish edition of Tintin. I 1965, his family themselves apparently went into comics publication business with the obscure Acar which would become an umbrella title for technical-legal reasons for their separate comics magazines, beginning with Aster the same year.
In 1967, the Şillilers began publishing weekly Bücür, which initially ran (unlicensed, traced, b&w, as always with the Şilliler family) Vieux Nick comics from Spirou and then Iznogoud from Tintin. With no. 13 (20.2.1968), Bücür began to run Asterix. For several years, Bücür alternately ran Asterix and other French-Belgian comics.
Sometime in the early 1970s, the ownership of the comics passed from Şarika Şilliler to Yaşar & Coşar Şilliler (later, Yaşar Şilliler would assume the ownership solely himself).
The last panel of each comics in Bücür is signed by Ayten Şilliler-Oflaz whom it can be assumed to have been responsible for the tracing job. The cover illustrations are signed by either her or Coşar [Coşar Şilliler] or Coşar & Serap [?]; only the first three issues were by veteran illustrator Hayri Önder.
The Şillilers took over Fatoş (Blondie) from Nihat Özcan in 1970 (published initially as Yeni Fatoş [New Blondie] and then simply as Fatoş) and Red Kit (Lucky Luke) from Bilge Şakrak in 1974; both magazines, as well as Süper Tarzan (1971 [Akim]), continued well into the late 1980s with endless reprints in several series, Short-lived titles put out by the Şillilers are Nik (1965), Tom Roks (1971), Küçük Prens (1972 [Johan & Pirlout]), Yuki (1973 [original Turkish juvenile adventure]), Altınkanat (1976 [Dago]), and Sipru (1977 [Spirou]).
