The bronze Mogente Warrior illustrated on this FDC is part of the 3v 'Archaeology' series from 2006. It was discovered in 1931 from Bastida de les Alcuses a 4th cent. BCE site whose destruction and abandonment remains a mystery.
Here are the other stamps from the 2006 'Archaeology' series. At left is an example of Iberian pottery; with fine clay, pale buff colour, concentric circles, horizontal bands and brownish-red glaze paint. This ceramic came from Alcudia, a large site that has occupation layers from the Neolithic to Visigoth.
Right shows architectural remains from the Copper Age site of Los Millares, driven by agriculture and animal husbandry. It is associated with defensive outposts and many megalithic tombs.
