I bought a large batch of German postcards a few months ago, and I've been slowly plowing through them. Got these beauties scanned in today.
They're private postal stationery depicting Saxon postal carriers, postal services, and postillion throughout history.
PP122 E6/01 -- Wolfgang Welck, Chief Post Office Director of Leipzig, 1752-1780
PP122 E6/02 -- Yellow coach between Dresden and Leipzig in 1770
PP122 E6/03 -- Electorate of Saxony Postillion in 1790
PP122 E6/04 -- Trip to the Leipzig Fair, 1800
PP122 E6/05 -- Post office with postal officials, 1852
PP122 E6/06 -- Saxon postmen and postillion before the royal post office in Dresden, mid-19th century
PP122 E6 -- Front of the cards with 3 Pf Hindenburg stamp indicia
The cards came as a set in a booklet commemorating "200 Years of Saxon Postal Service in Pictures".
Each card was cancelled with a commemorative cancel at the Saxon Stamp Show in Dresden, September 1938.
