Now very little concrete information is available on the unreleased trading card set. We do know that the set would have been 120 base cards (including 2 checklists) and possibly additional fold cards and bonus cards. They 120 card base set was to be broken into 3 subsets - Harbinger Reconnaissance, Harada's Assessment, and News Clippings.
I've done my best to label the pieces that have turned up by which of the three subsets I think they would have shown up in. Many are numbered and some even have notes written on them. My labels are just guesses though. I think the Harada's Assessment cards would have featured a portrait image and a profile image. According to information that was released these cards would have covered "Toyo Harada's personal thoughts on Valiant characters and their place in his schemes of power". The Reconnaissance cards were supposed to be "covert snapshots of Valiant characters in action, as seen through the lenses of Harbinger Foundation minions". A number of art pieces have "Recon" noted on them and depict action shots. A few others that are similar action shots have been labeled with a question mark.

The bonus chase cards would have been broken down into four sets - Eggbreakers, Harada's Archives, Final Battle and real life athletes who "are under scrutiny by the Harbinger Foundation, just as the Valiant superheroes are" as possible harbingers. As far as I know, no art from the Eggbreakers set has been released, and the Harada's Archives and Final Battle sets can be seen in my Valiant Files Card Set - An Overview post. Below are two cards that I believe would have been bonus chase cards from the Athletes set.

The art that follows consists of multiple key scenes from a particular Valiant title. I don't know what these would have been used for, they therefore have yet to be identified.
#?? - Shadowman (Various)
#?? - X-O Manowar (Various)
#?? - H.A.R.D. Corps (Various)
#?? - H.A.R.D. Corps (Various)
These final few pieces have been labeled The Valiant Files: Secrets of the Harbinger Foundation art but the pieces themselves give no indication, the art style is different and they don't look as though they would fit into any known section of the trading card set. They also have yet to be identified.
