1947-1954: small lot of unused 28 all different postal stationary cards, all with manual overprints like boxed "T.L.T" or L2 "TERRITORIO LIBERO TRIESTE". Some known variants like Filigrano C5A (the boxed "AMG-FTT" inverted), C5B and C8D, other unknown to the catalogue like C30 with additional manual overprint "T.L.T." or Italian C 144 (Quadriga rosso) with manaal overprints (3 examples with 3 different overprints). A nice study object. (Image)
