'THE INVENTION OF STAMPS - ESSAYS AND PRINTING TRIALS FROM THE FA PHILBRICK COLLECTION AND THE PRUSSIAN FIND' by Andreas Hahn. A very fine hardback (2008, 125 pages) bilingual text in English and German text describing the wonderful items held within the Philatelic Archives in Bonn, superb colour illustrations. Within the archive are wonderful items sent to the Prussian Post Office by the British Post Office in 1850 along with the Frederick Adolphus Philbrick Collection of GB early proofs and essays. Stunning. (Ref 78688).
