The O.VLASTOS LTD has been founded by Orestes Vlastos in 1973, but his love for stamps goes back to the age of 9.
In his early 20΄s and during the German occupation of Greece, Orestes Vlastos started his first business with stamps and in 1965 he made the first public auction of stamps in Greece presenting various rarities. In 1967 he presented the first catalogue of Greek stamps. In 1971 he became a pioneer by publishing the first full-colored catalogue in the world – which comes out every year, to the present – having won many prizes in national as well as in international exhibitions.
Since 1996 and after the death of Orestes Vlastos, O.VLASTOS LTD continues to be a family business and is runby Costas Greg. Sitarenios. By using the new technological means he upgraded the Greek catalogue of stamps and the auction catalogues keeping the company contemporary.
The philatelic approach in combination with many studies make O.VLASTOS LTD the only not purely commercial company. The last years it has extended its activities to coins, bank notes and all kinds of collectibles.
