Few of AFC’s younger readers are likely to know of Sidewalk Sam, although they may have seen his work–colorful, faithful chalk reproductions of iconic and lesser known paintings on sidewalks and plazas around Boston. Sidewalk has been creating his public art for more than 40 years. I came to Boston in 1971 so I cannot remember the city without the delight of stumbling upon his art. He is still working, despite a mid-1990’s accident which paralyzed his legs. Sidewalk is Robert Guillemin, a mid-1960’s graduate of Boston University’s College of Fine Arts, and BU Today has an article and video about his work and career.
