The following years were mostly devoted to small orders, but he returned to large decorative paintings in 1899, when he collaborated with Jan Preisler on panels for the pavilion of the Czech Chamber of Commerce at the upcoming Exposition Universelle in Paris. He worked with Preisler again, at the Central Hotel in Prague, then with Jaroslav in the meeting hall at the Italian Court in Kutná Hora (1901). During this time, he became an active member of the Mánes Union of Fine Arts. In 1902, he organized an exhibition for them in Paris and designed the posters.
