Inside the Musée de Cluny

We've already seen chess ouside the Paris museum Musée de Cluny (March 2013; 'In courtyard at Musée de Cluny'); now let's go inside. That post quoted Wikipedia's description, 'The Musée National du Moyen Âge', which translates to 'National Museum of the Middle Ages'.

The photo had no description, so we're forced to rely on the title. In English it translates to

Stained glass window : the chess players, 1450

The museum's web site has a page on the exhibit titled, Chess Players : Musée de Cluny. It says,

This panel of civil stained glass, produced in the 15th century, comes from the Hôtel de la Bessée in Villefranche-sur-Saône. [...] Though very popular among the cultivated aristocratic elite, few examples of civil stained glass remain today. • Height: 54.2 cm; Width: 54 cm

By 'civil stained glass', I understand stained glass outside of a church setting. The exhibit is also mentioned in Paris in Spring (chess-museum.com), which is a report on 'The 17th CCI [Chess Collectors International] World Convention - Paris, 2-6 May [2016]'. The page says,

In Cluny we not only found some well known chess sets of medieval origin, but also the fabulous glass window showing a lady playing chess with a gentleman of the times. [...] Superb scene of an amorously tinged chess game, beautfiul details -- window background, headgear, the checkered floor tiles, the back tapestry.

This is the second time in less than a year that I've mentioned Chess-museum.com. The first was Georgian Player, Regency Set (May 2020). How does one go about exploring such a vast repository of chess history?
