My choice for this week's theme may be stretching it a little, so whilst these stamps may not look se-tenant in terms of the image/design, they were issued together on the same sheet . . .
Issued by Egypt on 9 January 1960 to commemorate the laying of the foundation stone of the Aswan High Dam. (wiki link here).
The vintage postcard I have of the dam is undated, it depicts the earlier dam, the Aswan low dam.
