Senf of Leipzig published an international stamp album of extraordinary quality in 1878. It was bound in white vellum, tooled in gold leaf, with gilt edged parchment pages, and gold clasps. Having an original price of 60 gold marks, only a few albums were sold. One copy has survived in mint condition, with no stamps ever mounted in it. Heinrich Köhler will auction the album on November 3, 2012 at the International Philatelic Literature Exhibition, IPHLA 2012, in Mainz. The starting bid for the Senf album (Lot 9017) is 7000 €.
Besides this beautiful album, many other scarce titles are offered in the Köhler literature auction (No. 352) which contains 941 lots of stamp albums, monographs, atlases, postal regulations, auction catalogs, and journals. Although there is a strong emphasis on German literature, a wide range of countries are represented. The searchable, online version of the catalog unfortunately lacks any of the illustrations; a print copy can be requested from Heinrich Köhler.
