     REVIEWERS' COMMENTS -- Roger Brody, award-winning researcher and author -- "Having spent only a few hours with the Guide, it is clear that your work is a treasure of information, and most importantly the benchmark for understanding the complexity of the period rates and interrelationship of the stamps usage.  Clearly, many of the covers illustrated in the book (and the disc) are terrific..."
     Roland Austin, award-winning exhibitor and moderator of a Liberty Series Study Group -- "This is the most detailed source I have found on the Prominent Americans.  While it does not try to be the definitive study of the series, it does provide the collector with information needed to recognize important usages that might regularly be overlooked.  As well, it gives much detailed information about each stamp of the series.
     The suggested usages to look for had me going back through my boxes of old covers that I thought were useless for any further attention, but I had great fun discovering new searches...  To me, half the fun of collecting is searching and finding usages of different stamp varieties, and this guide helps lay out a search list of the Prominent Americans varieties.
     The Usage Graphs are an innovative visual tool to quickly view a particular stamp's possible usages during a given rate period. This is truly a field guide that a collector of the Prominent Americans Series should not be without."

(FROM E-BOOK's BACK COVER...)
   What's interesting about a set of regular U.S. stamps from the 1960s?  Just about everything that makes any 
period of U.S. postal history a collecting or research challenge...
* over two dozen designs in different values, issued for the "workhorse" postal needs of the 1960s & ‘70s…
* regularly issued phosphor-tagged and untagged varieties, starting with the early years of the U.S. Post Office's Luminescent Tagging Program…
* highly detailed steel-engraved die varieties, some of which were used for stamp formats without advance notice, allowing “earliest documented use” searches…
* little-publicized color varieties that can be searched for…
* dozens of surprisingly short “windows” of usage availability -- tremendous search challenges for stamps on-cover paying certain rates…
… just to name some highlights!
   Use this guide to discover the wide variety of collecting or research challenges that await the postal history student or stamp collector looking to specialize.  Over a hundred pages include stamp information, usage pictures and 12 in-depth articles.  Exclusive “Usage Graphs” fill another 128 pages, listing various uses for the Prominent Americans stamps that rival any other series for fun and interest in finding actual examples.  Over 300 pages total, plus more mini-stories in bonus material.
   (With companion CD showing the guide's covers in full color and enlarged, plus much more in bonus material.)
