2 different covers:
Cover A, the direct sales edition, contains no upc on lower right hand side, and has the 1-800 number fans phoned in to determine Jason Todd's fate on the inside of the issue itself.
Cover B, the newsstand edition, released 3 weeks later, contains the upc code on lower right hand side, but doesnt have the 1-800 number on the inside of the issue.
The Direct Sales copies of this comic, released first, contained a 1-800 phone number to either vote "for" or "against" the death of Jason Todd on the inside back cover. The newstand copies, released 3 weeks later did not contain the 1-800 number.
