-Comment: Many boys (at different age, mostly younger boys) in different Lederhosen. Buckskin, some with suspenders, but also older boys in smooth finish or nappa Lederhosen (brown maybe also black, some with 2 zippers). Not sure if teens as well. And not sure if Lederhosen in all episodes but there might be often kids. Pic is from ep 13: Clown Ferdinand und das Fahrrad.

I watched this series in the 1980s or 1990s. I can't remember all episodes and I think I even still have some parts on VHS (but in bad quality). According to IMDb this is a 1973 TV series. Other sources say TV series 1955-1975. There are obviously additional CSSR movies like "Clown Ferdinand und die Rakete" (1962) and Clown Ferdinand an Bord (1959). He also appeared since 1955 in "Zu Besuch im Märchenland" which might be a different series.

Clown Ferdinand is played by Jiří Vršťala (1920-1999). Series by  Jindrich Polák.

Also cycling scenes and close up scenes of Lederhosen.
I have to check this series completely, not sure if I should buy it.

Even rating 9-10 for now. However most kids are very young.
