Beautiful rainbowy collection!
It is somehow a digital collection, because the stamps are spared in boxes of postcards and letters... :)
OK - that's a challenge to send you some you haven't got whilst at the same time still sending commemorative ones as well.
It wasn't intended as a challenge for my UK friends! In fact, I think is difficult to complete this neverending series...
Thank you for coming. All your comments make me extremely happy.
