1972 Reykjavik, Utgafudagur, Iceland - First Day Cover - has the date 2. VII. 72 on the envelope. The stamp, which has 15 KR value, has the date 1972 and a picture of a chess board on it. That was the year Bobby Fischer was to have played the world chess championship there (He didn't show up, I think...not sure). This First Day Issue is a pristine preserved part of history that would add to your collection.
