After reading the given texts I can summarise that Leo Steinberg wrote a book in 1972 called ‘Other Criteria’ containing essays, one of which he explored ‘The Flatbed Picture Plane’. The Picture Plane I believe is a flat surface; a symbolic allusion for hard surfaces such as table tops and studio floors where data is entered in different ways from different materials by different artists. Steinberg talks about various mark making methods such as printing and painting including a flatbed printing press. He also talks about the picture plane of the 1960’s in correspondence with the erect human posture touching on realism, cubism and abstract expressionism. He defines the term flatbed as changing the relationship between artist and image, image and viewer.

Furthermore, the article on Richard Serra is based around his sculpture work and informs the reader that in the late 1960’s he began three-dimensional works exploiting heavy materials and their properties. In the 1970’s and 80’s he worked with steel units and his work maintained a critical presence. Unlike Steinberg, Serra relies upon industrial sector to build work and relates to the urban landscape and architectural enclosure producing work outside of the studio focusing on the relationship between sculpture and context. The use of materials and location matter to Serra, where as I feel Stenberg can relate more to a studio practice and a flat surface. Both artists mention Picasso and Warhol in their work but from different angles.
