Dubai issued this postal card honoring the Dubai Scout Movement with numerous varieties.

Due to the popularity of the Scout topic the issues were heavily "played" with and many errors were created.  In thirty years of collecting I have never seen a genuine postally used Dubai postal card.  The issue, along with several of the 1964 aerogramme sets, had a variety of "SPECIMEN" handstamps, in Arabic and English, applied to them.  These handstamps exist in every combination possible (with the exception of being placed vertically on the cards).  They are found with a single handstamp, double, one inverted, both inverted, one normal with the other inverted and with the Arabic removed.
