FDC - Bloc 50 years of Luxembourg Flag

The “50 years of the Luxembourg flag” souvenir sheet marks a first for POST Philately. For the first time ever, lenticular technology was used for printing and processing. Thanks to the use of lenticular film, which enables you to see different parts of the motif depending on the angle at which it is held, it looks like the flag is flying on the stamp.
