These are Duplicate British stamps. All commemoratives and all available for Trade and Exchange. New sheets will be added over the next couple of days. Around 250 British stamps (definitive, regional and commemorative) will be available. In some cases, I have multiples of these Duplicates.
If you are interested, please let me know. I want to trade with as many people in as many places as possible so I will limit the number of stamps, I send to any one person to TWENTY-FIVE.
