The Guatemalan authorities announced that an agreement had been reached with the USA for the return of a carved stone Mayan frieze. This return adds to over 10,500 disputed artefacts already returned to Guatemala from around the world in recent years.
Whilst I always assert that every cultural property dispute is different & should be dealt with on its own terms, it is still easy for anyone to see the parallels between one carved stone frieze & the Frieze from the Parthenon (part of which is currently in the British Museum.

The impressive frieze of Maya returned to Guatemala
The Guatemalan government officially announced the return of the U.S. giant Mayan frieze dating from the classical period, between 250 and 900 BC. The restoration and maintenance procedures were completed and returned the frieze in the country.
This is a work of art from limestone, which is a height of about 50 cm and was located in the northern province of Peten, a region considered the birthplace of the ancient Mayan civilization.
The last 10 years, Guatemala has recovered more than 10,500 antiquities that were in other countries, such as USA, Germany, Britain and France, after the La Corona and other archaeological sites in the Petén looted in the 19th century.
