1 October 1945
Luxembourg issued two postal cards on 1 October 1945: a 75c card featuring the Grand Ducal residence at Colmar-Berg paying the domestic rate and the rate to Belgium, and a 2.00-franc card for UPU use (including Germany).
The rate to France was set at 1.50-franc as of 20 Feb 1945, but a card was not issued for that rate.
The card shown here was sent on the first day of issue by J. P. Wallenborn, a well known Luxembourg stamp dealer, to the postal stationery enthusiast, August Wery, in Belgium.
