Moroccan and Serbian bridges

Diplomatic relations between the Republic of Serbia and the Kingdom of Morocco were established on March 2, 1957. So, 65 years later, why not celebrating this anniversary with joint issue illustrated with bridges? The two architectural structures shown on the stamps represent the new Road-Railway Bridge over the Danube in Novi Sad, built in 2018 (474 m long and 31.60 m wide) and the cable-stayed Mohammed VI Bridge in Rabat, opened in 2016 (947 m long) which is the largest cable-stayed bridge in Africa, with the tallest concrete and steel viaduct in the world. The stamps were issued on March 1, 2022.

Unilateral issues 2021 ?

On December 10, 2021, Serbia issued an unexpected souvenir sheet at the occasion of the 25th anniversary of the relationship with Kazakhstan. Stamps represent the two capital cities, Nursultan and Belgrade, and the souvenir sheet has a shape ideal to be produced as a joint issue. Unfortunately, no information is available from Kazakhstan so far. There is a high risk that this issue, probably initially planned as joint, will remain an unilateral product.

A similar situation may take place with Austria, which issued on December 6, 2021 a souvenir sheet also designed like a joint issue. This product initially planned to be released in June 2021 was somehow announced as potential joint issue with Greenland. As for the previous product, this souvenir sheet may remain unilateral, as no information is available from Greenland so far.
