Hello,  today  let's move to Gibraltar.    Here is a  nice looking stamp from the 1938 GVI issue showing the Rock, actually Europa Point.  Nice  Field Post Office cancel as well.

A  Field Post Office ( often  it will just show as FPO in a cancel) is a post office set up during a time of war or when a military unit  in on manoeuvres.  FPOs can be on land or at sea.  Makes for an interesting collecting area.

This stamp like many other GVI British Commonwealth issues from this period provides plenty of opportunity to  enjoy the study of the stamps and to look for the various perforation, colour and watermark varieties.  Do look out for a mint copy of this stamp with a perf 14.  Very nice catalogue value.

Enjoy   Michael  cddstamps.com     and  with thanks to my friend at  British Commonwealth Album  here   -  and you might enjoy a visit to his online store  the Used Stamp Collector here.
