"For Doug I-10" is a wall drawing by Sol LeWitt created as a tribute to fellow artist Doug Wheeler, exemplifying LeWitt's systematic approach to geometric abstraction through simple linear instructions. The work demonstrates LeWitt's conceptual practice where the idea or set of rules is paramount, allowing for execution by assistants following his detailed written directives rather than requiring the artist's hand. Like much of LeWitt's oeuvre, the piece can be erased and redrawn, emphasizing the immaterial nature of the artwork as a concept over its physical manifestation.
