Britain's secret little post office at Bletchley Park is celebrating England becoming the World's Number 1 cricket team with a special stamp issue.
The hand prepared stamp and envelope combination features two exclusive paintings by renowned cricket artist Christina Pierce, one on the envelope and another on the stamp.
The stamp has a 13th August 2011 postmark to mark the day of the big win.
Only 500 are being issued at £8.50 plus £1.50 (UK) post and packing. Bletchley Park Post Office issues sell out quickly and can fetch many times more than the issue price.
