Who drew these? Rogan's strips were usually signed by "Masip", and Whizz Wheels was unsigned.
(before anyone says - Brian Walker drew the final series of Whizz Wheels, a BMX three-parter in 1983 or so - the last Rogan series was Rogan on the Run, with Ralph on the run for a crime committed by his accuser as he travelled from Tampa to the 1984 Olympics.
