The museum is showing a rubbing of a Tang dynasty stone tablet.
Tips
culture
Rubbings were how a stele's text travelled before photography. The stone wears a little with every rubbing, so an early, sharp 拓本 of a famous stele is collected and prized like a painting.
mistakes
拓 is read tà in every rubbing word: 拓本, 拓片, 拓印. Elsewhere it is tuò, to open up, as in 开拓.
