Ray Green posted the following comments on todays' Pic of the Day from the '57 Chicago "6";
"something of a mystery. Tressider appears to be wearing a rainbow jersey but I don't believe he was ever world champ at any discipline. Nor was his partner Herbert Weinrich. It was Peter Post's first win in a Six day and Ted was second at just one lap."
So, can anyone shed more light on Tressider/Weinrich's apparently rainbow jersey?
