This book was unknown to me for quite awhile. It is probably the best resource that captures the most amount of GI Joe: A Real American Hero action figures, well past 1994.
Written by Chris Cardillo and legendary Joe collector James Desimone, this book takes you through every Joe figure and it's accessory, along with a numbering system that will help collectors identify their soldiers.
The book retails for $29.99 at Amazon.
Once again, I almost missed posting today. Reminds me of that elementary school book - How to Eat Fried Worms, published by Thomas Rockwell in 1982. The connection is a long story.
