Sceaux armoríes des Pays-Bas et des pays avoisinants (Belgique--Royaume des Pays-Bas--Luxembourg--Allemagne--France) recueil historique et héraldique
A four-volume historical and heraldic catalogue of armorial seals from the Low Countries and neighbouring lands, compiled by J. Th. de Raadt and published in Brussels in 1898 for archivists, genealogists and heraldry scholars. The plates are halftone photographs of wax seal impressions, each a worn circular disc carrying a shield, an enthroned or mounted figure, and a Latin legend running around the rim; useful for circular badge layouts, medieval lettering rings, eroded relief texture and shield shapes.
