1938 VOORTREKKER CENTENARY DANSKRAAL PIGEONGRAM: Original pigeongram flimsy from the celebrations held at Danskraal in Natal on 7th December 1938 by a re-enactment group under the leadership of H P Klopper. The pigeongram is printed on rice paper with the text of the Voortrekker Blood River vow and red underprint of the Church of the Vow. An extremely rare piece of which we record only two examples extant. Ex Jeidel & Polakow. See additional image below.
