I found this link on another site, so I sent away for it.  I received it already.  I just ordered it last week.  It is a very nice packet.  It has large posters and smaller posters.  They include pictures of different types of seeds, leaves, and one that explains how to read the rings on a tree.  It has wonderful graphics and is easy to understand.  A must have for the nature lover.  I think the small posters would fit nicely in a nature notebook and make easy reference material.  Oh the possibilities!
