2022Provisional Stamps - First Day Cover block of 4

After almost ten years, Philately Liechtenstein is again using the overprinting method for two of its existing definitive stamps. In this procedure, which used to be very common, the original face value of the stamp is visibly corrected and overprinted with the new face value. The price increases of Liechtensteinische Post AG have made this necessary. As of January 2022, it will increase the prices for A mail letters by 10 centimes (new CHF 1.10) and for B mail letters by 5 centimes (new CHF 0.90). This is the first price increase for letter mail in seventeen years. Stamps that have already been issued will remain valid.
