1918 1f to 50f Postage Due Set for Croatia-Slavonia, all in mint hinged blocks of 4, each stamp has an overprint and the 50f has the rare Crown watermark variety (2LJ1, cat. $650 per stamp). There is slight separation on the 50f block, still overall fine, and we cannot attest to the authenticity of the overprints, except to say we've seen them like these before (whether good or bad).
