PI Flights CD

At the 2016 New York World Stamp Show, the USPPS issued an informative colorful booklet designed to introduce collectors and other visitors to that international exhibition to the broad range and depth of United States Possessions philately.
A small number of the booklets are still available for those interested in acquiring one.


In 2018, the Society released a publication dealing with Puerto Rico's postal history during the period of the Spanish American War. This fascinating period of philatelic history is detailed in great depth in "Puerto Rico During the Spanish American War, 1898-1900", which was awarded a Large Gold and received the Postal History Society's Literature Award at the 2018 APS StampShow in Columbus.


Prepared from years upon years of extensive original research, the series of works known as "Napp's Numbers" are classics in the realm of philatelic literature associated with the U.S. Possessions. Now in electronic form for ease of use.


After years of research, USPPS member Gregg Greenwald released a reference work in 2021 covering revenue issues of Puerto Rico from 1898 onward. Titled "Catalogue of Puerto Rico Revenues - U.S. Administration Sept 1898-Present", this is a 196 page in-depth catalogue of the complex revenue issues of this period in Puerto Rico, and is the most comprehensive catalog of Puerto Rico revenues ever published. Bound with card covers, this publication is considered to be a 'must have' reference for collectors of Puerto Rico.
A copy can be obtained from (a) Amazon (search for "Gregg Greenwald") and from (b) well known revenue dealer and fellow USPPS member Eric Jackson in Leesport, Pennsylvania and via his sales on Ebay.
The author advises you can purchase an autographed copy directly from him at Gregg Greenwald, 2401 Bluebird Court, Marshfield, Wisconsin 54449.       He may also be reached at bluebird@tznet.com for further information.
