This is a collection of Warplanes index/fact file cards that began being printed in 1989 by Edito-Service S.A. They are in an original storage box that is labeled on the front "Warplanes Collection". They are divided into sections with oversized dividers for quick & easy reference. The categories they are divided into are:

I. - Light Bombers
I. - Medium Bombers
I. - Heavy Bombers
I. - Torpedo Bombers
I. - Dive Bombers
II. - Fighters
II. - Air Superiority Fighters

VII. - Reconnaissance & Observation
VIII. - Transport & Utility
IX. - Famous Dogfights & Raids
X. - Aces, Engineers & Builders

There are also some transfers or iron-ons of some kind that are included, some of which are pictured. I don't know how many cards are in this box, but there are at least a few hundred.
