His poor health leads to Sauer gradually focuses more on drawing. An important subject matter is the (female) nude. He does however remain active as a decorative painter.
On the technical front Sauer is also innovative. To accentuate the ivory skin of the model, the artist brushes his sheet with bees wax. Gold and silver plate sometimes form a frame around his drawings.
Sauer establishes an international reputation as a decorative artist in the twenties. He represents Belgium at the Exposition internationale des Arts Décoratifs (International Exhibition of Decorative Arts) in Paris, which lends its name to the Art Deco.
When he receives the commission to decorate a Byzantine room with scenes from the life of Christ, Sauer travels to Spain and Algeria for inspiration. He dies there unexpectedly at the age of 38.
