The Raspberry Pi is about to make an appearance on envelopes all over the UK as part of a set of stamps celebrating British Engineering.but you can't lick them - they come sticky backed.

The Royal Mail is issuing a series of six stamps celebrating 50 years of British Engineering.

You can buy your own presentation pack at the Royal Mail website (or at Post Offices) now.

Can the Pi really be classed as "British Engineering" when so many of its major components are from other places?
