Penetration 103 is one entry in a numbered series through which Tsubota examines the spatial event of one form entering or passing through another. The title implies directional energy, and the composition likely presents intersecting planes, vectors, or layered color fields where one element visually breaks the boundary of another. The dual-medium technique — lithography combined with silkscreen — enables distinct surface qualities to coexist: the lithographic ground may read as atmospheric or granular while silkscreen overlays define crisp edges. The high series number indicates sustained engagement with this single formal problem, consistent with Tsubota's practice of exhausting the possibilities of a given compositional premise across many iterations rather than resolving it in a single work.
Penetration 103 was created by Masahiko Tsubota (坪田政彦).
Penetration 103 uses Silkscreen and Lithograph, on lithograph / silkscreen.
