Luxembourg has issued just 1 stamp on 16 April 1958. The stamp was designed by Lex Weyer and printed by Courvoisier.

The stamp depicted the Luxembourg Pavillon at Brussels Expo.

It is important to note that on the same another stamp was issued in a similar design but which has nothing to do with Brussels Expo 58. It was a stamp to celebrate the 10th anniversary of an exposition building in Luxembourg. Often covers are cancelled with both stamps since issued the same day.
