Gibraltar Study Circle
The Gibraltar Study Circle exists to study the stamps and postal history of Gibraltar, a British overseas territory located at the entrance to the Mediterranean Sea overlooking the Strait of Gibraltar.
The circle was founded in 1975 by Walter Jackson and is based in the United Kingdom but with worldwide members.
A journal, The Rock, has been published since 1975.
The circle is not to be confused with the Gibraltar Philatelic Society which is based in Gibraltar itself.Selected circle publications
