THE MAP STAMP STUDY GROUP of the BNAPS     What is the Map Stamp Study Group? We are a group of philatelists who are interested in studying the Map Stamp and in receiving news of various observations which have been scutinized by other like minded philatelists, and in discovering more about the design, printing, and usage of this stamp, as well the colour changelings and retouches and various idiosyncracies associated with the stamp.   WHAT DO I GET FOR MY MEMBERSHP ? EACH MEMBER OF THE STUDY GROUP IS ENCOURAGE TO SUBMIT THE RESULTS OF HIS RESEARCH TO THE EDITOR WHO PREPARES A  NEWSLETTER FOUR TIMES A YEAR WHICH PROVIDES UP TO THE DATE INFORMATION ON THE VARIOUS NEW ITEMS, AS WELL AS FURTHER INSIGHT ON PREVIOUS RESEARCH,
