"Hi Thanks for posting these. Something for you to look out for: I have a book called Zepplin Post Katalog by Sieger-Verlag it is 419 pages full of These Airship stamps and 1st Day covers and the official postmarks from Zepplin flown mail."
"Yeah I bought the first 4 issues. It's glossy and full of style, very visual with not any real reading. Great if your really into the 'Golden era' as they put it. There's only ever been 5 issues so not an on going money well.…"
