Firstly I shall add Sealand's first stamps, which was a set including history's most famous maritime explorers, along with a drawn picture of Sealand and a helicopter, the helicopter being the method of transport used for delivering Sealandic post to Brussels in Belgium.
The next image shows both sides of a very rare envelope to Beunos Aires in Argentina.
Not only does this envelope have some of the more early Sealandic stamps attached (displaying famous ships, with the SX$1 stamp displaying Dutch and English ships at war) , it is once again another example of how microstates have sent post without the services offered by recognised postage systems. You will also notice a map indicating the location of Sealand stamped on the front of the envelope.
There are many more Sealandic stamps contained within the collection, and scans of these will be uploaded in the near future.
