I remember someone mentioning that it would be interesting to find a particular post card that was printed in Germany that shows various stamps of Guatemala on the picture side. It is rather common in unused condition and somewhat common used from Germany to Guatemala.... but what about it being used from Guatemala ? Well I found one used from Guatemala (via New York) mailed to Darmstadt Germany in 1906. Enjoy!
