The term “Se-tenant” in philately describes unseparated stamps and labels printed from the same plate in a pair, strip or block which have a different design, colour, denomination or overprint. Se-Tenant is a French word which means “joined together”. Se-tenant stamps have a continuous design.
The above are examples of ‘Se-tenant’ stamps from the 1933 Italy Balbo’s Trans-Atlantic Flight Issue (Scot C48/C49) also referred to as a “triptych” which is a phrase used in the world of arts and basically means in philately, a set of three panels hinged together.
