With the vivid and impasto variegation of his paintings, the striking forms and particularly with the repetition of motifs Schubert`s formal language sometimes reminds the viewer of folk art. Masks, animal motifs, floral and architectonic elements, as well as abstract ornaments are interwoven to puzzling and mythical figures. Not a realistic depiction or story telling is decisive, but the expression focuses on a strong emotional charge of the pictures. The prints are extremely complex. Either Schubert compiles varied motifs on one plate or he puts several layers above one another on his large size prints, so that different individual motifs form a new figure. He counteracts the possibility to reproduce a linocut by reusing motifs, but he solely creates unique prints. The emerging traces of work and differences of the cover remain as characteristics of the printing process, as they give proof of the authenticity of the print and its uniqueness.
