Lots of stamps on this little cover from Argentina. The miniature sheet from 2017 on the left commemorates the 200th anniversary of the crossing of the Andes mountains in 1817. In the middle is a stamp commemorating the 90th anniversary of diplomatic relations between Argentina and Bulgaria. The round stamp on the right is from a 2021 miniature sheet that explains solar eclipses. And the two above the address are "Unidad Postal" stamps from a 2019 (I think) series about national parks: Parque nacional Aconquija on the left and Parque Nacional El Leoncito on the right.

Postmarked at the Charleroi X sorting centre outside the city of Charleroi south of Brussels. The row of stamps along the top are a set of semi-postals from 1974 that celebrate Belgian cultural celebrities. In the bottom row are a pair of Belgian bird definitives and the on the lower left is a 2018 coil stamp featuring a gooseberry. It's a nice little cover.
