Denmark: 1912 Zeppelin use of Numerals 3o Postcard uprated Numeral 5ore tied by 'Kjobenhavn 19 9 12' cds (other stamps uncancelled), both sides with 'An Bord Des Zeppelin Luftschiffes Hansa 19 SEP 1912' flight cachet. (It appears that sender put many stamps on the card but PO clerk only cancelled the 5o value as that was enough for postage, & rest of stamps were roughly removed, while later other stamps affixed over those areas of card). Sieger 5A cat €3000. Great rarity of early Zeppelin flight outside Germany, only several recorded. (P) (Image1)

Estimate AU$2,000
