The Royal Mail's Trooping the Colour range of stamps was wheeled out for the first time yesterday at Birmingham's oldest company - military insignia and button manufacturer Firmin & Sons.
The New Town Row firm - established in 1677 by button maker Thomas Firmin - is one of the few in the UK to hold three Royal Warrants at the same time.
It can trace its royal connections to George II when it obtained the Royal Warrant of Appointment as button manufacturer to the monarch. It also supplies uniforms, swords and the breastplate armour for the palace guards.
The new stamp feature images of the Queen, Prince Philip and troops from the Household Guard.
Firm chief executive Malcolm Benson said: "As the oldest firm in Birmingham with three royal warrants, it is fitting we should be asked to help Royal Mail reveal its first stamps to honour the Queen's birthday parade."
