John,
I agree with Barry. It's sometimes hard to tell good FAKES from original factory brochures just from photographs. However, there are some things to look for. The first is a slight yellowing around the edges of otherwise white pages. This yellowing is due to aging, and is a good sign that the item may be old and original. If you have one you know is original, comparing the staples, if any, in the brochure may be telling. Also, many FAKES are marked as such.
