As David Thomas wrote for the excellent and long-running online magazine Perfect Sound Forever, back in 1998:
Rob Tyner’s graphic art, while largely unknown outside of a small circle of family and friends, testify to his formidable abilities as a visual artist. From his days as cartoonist for Detroit’s Lincoln Park High School yearbook, Tyner drew cartoons which demonstrated his unique wit and world-view as well as his formidable drafting ability and artistic vision. Detroit’s Grande Ballroom poster artist, Gary Grimshaw, a high school classmate of Tyner’s, has said that Tyner "was a much better artist than me then - he could draw anything." The most readily viewable example of Tyner’s cartoon style can be seen in the MC5’s High Time LP jacket artwork and accompanying full-page ads which ran in Billboard and Cashbox.
He also drew MC5 handbills throughout the band’s career and contributed cartoons to Detroit’s underground paper, The Fifth Estate, particularly in 1966. His unpublished works include a wonderful series of alphabet animals for children, numerous hot-rod and fantasy character drawings (in which his love of Science-Fiction is readily apparent), and a particularly comical series of caricatures of John Sinclair and other Trans-Love personalities. Letters he wrote to his young son while the MC5 where on tour in England and Europe from 1970 to 1972 contain many cartoon strips that serve as travelogues of his experiences and a window into the soul of a warm and loving family man.
