The stamps will be issued in self-adhesive miniature sheets of 6 stamps with information in the margin.
EDIT: The stamps will be on sale by mid-day the next day at 500 Post Offices. An additional 4500 Post Offices will receive the Gold Medal stamps within a week.
There will be one for each gold medal, individual or team. In the event of an individual winning more than one gold, then they will get two different stamps using pictures from the event where possible. If there is more than one gold on in a day, then there will be two stamps/MSs the next day. Royal Mail FDCs will carry the complete miniature sheet of 6. Only one style of postmark will be used.
The Royal Mail press release said that stamps would be available singly, but we await confirmation that postmasters will be expected to separate stamps from the MS.
UPDATE: Stanley Gibbons catalogue editor confirms each gold medal stamp will be assigned its own SG number providing the stamps are readily available.
More technical information on our webpage.
Further update: We understand that postmasters will be told that single stamps may be sold. This probably means the use of scissors!
The location of the digital overprinter (but not the name) will be shown in the selvedge of the A4 sheet at bottom left.
