Graham's work was always firmly based within conceptual art practice. Early examples were photographs and numerological sequences, often printed in magazines, for example "Figurative (1965)" and "Schema (1966)". With the latter Graham draws on the actual physical structure of the magazine in which it is printed for the content of the work itself. As such the same work changes according to its physical/structural location within the world. His early breakthrough-work however was a series of magazine-style photographs with text, "Homes for America" (1966–67), which counterpoints the monotonous and alienating effect of 1960's housing developments with their supposed desirability and the physical-geometry of a printed article. Other works include "Side Effects/Common Drugs" (1966) and "Detumescence (1966)".
