Great Britain 1911 ½d green (Die 1a perforations 14), SG322a.
A very fine used example of this difficult to find perforation variety neatly tied to a picture postcard of Wellington Gardens, Great Yarmouth by a crisp Great Yarmouth double ring circular date stamp for 'AU.28.1911'.
A most attractive and scarce usage of this rare printing variety of the first stamps issued in King George V's reign.
