In need of a memorable way to celebrate the launch of the long-awaited Air Jordan XX3 in 2008, Jordan Brand gave fans an opportunity to relive the entire history of the line by re-releasing each previous model. There was a twist though — the shoes were paired off into groups of two models that added up to ’23.’ For example, things got underway that January, when Air Jordans 10 and 13 were boxed up in two original colorways that hadn’t yet been retroed.Air Jordan Countdown Package CDP Pack (or Collezione) shoes were packaged in a special fold-out box bearing graphics of the first 22 Air Jordans and a special message from Michael Jordan himself. Retail was set at $310. Following the January launch, the Air Jordan XX3 was released in February and packs were then released in subsequent months for the rest of the year.
