The museum website says: "To create these panels, silver leaf was glued to leather hide and then coated with layers of yellow-tinted varnish to give the hangings their rich, golden color." I asked the attendee in person how they maintained them, and he said he didn't know lol

i used their website's photos to compare individual panels and learned they are all individually painted. as for maintenance, it looks like the panels are aging very badly, especially around the edges... hopefully they are applying some sort of varnish periodically

i was under the impression they were all masterfully replicated from a single template but nahh once you can see the strokes you could see how they might have painted each one referencing the previous panel, slowly drifting from the original painting, then shuffled around before assembly

yeah, I don't believe there was much of an existing mechanical method for copying oil paint from a template; it was largely something that had to be done by hand. Also, the attendant did point out some of the cracks in the paint, of which there were many, to indicate the aging.
