I believe this illustration is by Rene Stoute.
"Oef" in Dutch means "phew."

This postcard was sent by MoniqueN.

This card bears no postmark.
It was registered after 40 days of transit.

On Monday, 02 November 2009, I received from my dear Postcrossing friend, nordbär, this postcard of postmen from 1866 Saxony. I lubber me some mail-related mail! :D

EDIT: It would appear this postcard was published to commemorate 500 years of mail delivery (500 Jahre Post).

Some German words I learned are:

• Briefträger = Postman
• Post = Post office
• Postkarte = Postcard
• Luftpost = Air mail
• Jahre = Years
• Jubiläums = Anniversary
• Nord = North
• Bär = Bear
