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 antiquarians, archivists and heraldists. The plates are halftone photographs of wax seal impressions, round and pointed-oval, showing shields of arms, mounted knights, standing figures and Latin legends in Gothic letters around the rim, with mottled, worn surfaces useful as circular emblem frames, lettering models and grainy texture.
