Well, thanks to a foot of snow, I am getting to enjoy a day off and I finally have the time to really get into this book:
The Ultimate Action Figure Collection
by Steve Sansweet, Dan Curto, and Paul Harrison
Of course I have known Paul from Jediteimplearchives.com for awhile now and think Sansweet and Dan need no introductions either, but seeing this picture database, arranged in alphabetical order, makes it so easy to navigate. This covers over 2,500 action figures produced in the last 35 years. If you are a 3 and 3/4 inch collector I can't see how you wouldn't want this. I haven't put mine on the bookshelf since I got it as I am always referring to it. With the way Hasbro is doing action figures these days there is a good chance the one you already own is better than the new version and this resource lets you know. It will save you some coin!
