Very happy to have a cover from San Marino in my humble collection! The 1st stamp is from a joint issue with Slovakia from 2007, showing the 13th-cent. Orava Castle in north-western Slovakia. The 2nd was issued in 2001 and is from a set of 5 showing French painters - this is Post-Impressionist Paul Cézanne.
Another great addition from Luca, thanks so much! The cancellation is also gorgeous :))
