In 1983, stamps specifically inscribed "Alderney" were issued by the Guernsey Post Office (now Guernsey Post Ltd) which were principally designed to be used on mail from Alderney although they are valid for postage anywhere with the Bailiwick.
This thread lists chronologically all stamps issued since 1983 to date (and into the future) to provide a visual reference.
The format will follow a number of other more established ones and each issue will have an introductory post showing all the stamps in it, together with the issue date, official text from Guernsey Post surrounding the release (taken from the insert in the FDC/Pack) and other common details.
There will then follow a series of more detailed posts showing:
1. each stamp / min sheet in greater detail (with an expanded description)
2. the official FDC(s)
3. cover of presentation packs
4. booklets and booklet panes
5. anything else that comes to hand
The next post contains an index of the issues which will allow you to jump straight to the start of the section for each issue.
By all means add extra information and I will move it into the correct section (and acknowledge the poster).
