I thought I had used all my se-tenant stamps before so I went to my favourite market stall this week where I found some Libyan stamps (the first I had seen).
|Libya - Tokyo Olympics 1964|
I like the way the Olympic rings are used across the block. By the way Libya did not win a medal that year.
I also discovered that what I thought was a strip of stamps was actual part of a se-tenant strip issued in April 1972 to commemorate the USA National Parks Centennial.
|USA - Cape Hatteras National Seashore|
