Appel shared Dubuffet's embrace of raw gestural brushwork and childlike figuration, building up thick impasto surfaces with figures and animals rendered in bold, spontaneous forms that reject academic refinement in favor of primal expressive energy.

As a founding member of the CoBrA movement, Jorn created densely textured oil paintings where figures and landscapes merge into unified fields of earthy and vivid tones through agitated mark making that closely parallels Dubuffet's Art Brut sensibility and rural subject matter.

Chaissac was a self taught artist deeply connected to Art Brut who produced naive and whimsical figurative compositions with scratched and roughly worked surfaces, sharing Dubuffet's rejection of refined technique and his celebration of untrained visual language rooted in earthy rural forms.
