This is a 100 card box collecting the 50 cards from the base game and 40 from the 4 card expansions (while each expansion had 20 cards, they were all doubles, so there were only 10 different cards in each) and 10 from the miniature bonus pack. It also contains one random Snarf Miniature.
The rules poster credits Agents of Gaming, but the box only lists Elmore Productions. The set contents appear to be a repackaging of leftover stock from the Agents of Gaming edition that could have led to this discrepancy.
The box was first distributed at conventions in 2002, and is sometimes called the "Gencon 2002 Box" or "Origins 2002 Box", or similar nomenclature. The boxed edition was also made available online at etailers like Paizo.com, but now appears to be OOP.
