Query: Disappointment

The books title states 'collectors guide'. Yet there is nothing about how to date and read the stamps on the bottom. While it show the years a pattern was made it did not identify all the ways sets were sold. I also found errors in what sizes patterns were made. The value I did gain was seeing some patterns I did not know about. I do not see the value in the book for myself. I learned more on the Internet.
