Bicycle Rider Back Red, Ohio printed, blue seal, bottom barcode on left

Although there seem an infinite number of varying rider backs made, there are noticeable tuck details that define one from the other. Details range from where printed, year (if present), blue or black seal, location of barcode (if present), tear strip variations (clear or white, bicycle printed or blank), advertisements, single or double printed border stripes, bottom of tuck printing color, etc etc. As well, the ace of spades of any deck will carry a code that can be researched to provide the year of printing. If cataloging in detail, always check for any minor variations.
