Question: What is the significance of having a white square in upper left corner of checkered flag or a black square in upper left corner of checkered flag ? Catalog gives you an option but what was the original design or did they come either way ? Maybe it doesn't make any difference ? Just read the listing on page 45 ZIP Catalog C2 1963-1967 Thanks !!

 

Maybe it has to match the crossed-flag emblems elsewhere on the car. Or youi could call Zip.
