Se-tenant

Se-tenant stamps or labels are printed from the same plate and sheet and adjoin one another, unsevered in a strip or block.

The word "se-tenant" translates from French as meaning "joined together"[3] or "holding together".

With the issuance of U. S. national postage stamps, which began in 1847, se-tenant production disappeared from the nation for 117 years, not introduced until the 1964 Christmas Issue, which presented images of holly, mistletoe, poinsettia and a conifer sprig in a block of four stamps.

The US has since printed as many as 50 different stamps on a single sheet, such as in the 50 state flags, birds and flowers.

Se-tenant stamps began as issues of separate designs that were simply attached to one another, but have developed to issues where the stamps are part of a larger continuous design.
