A complete set of 20 original rubbings of the "Longmen Twenty Inscriptions," with a certificate of guarantee from the Longmen Grottoes Research Institute, housed in a paulownia wood box. This is an item left by my deceased older sister, who ran a calligraphy school. It is believed to have been purchased in China. Although it has been stored for a long time, the folds appear to be as they were originally. I have taken a series of photos, so please check the condition in the photos. Outer box dimensions: 26.5cm (height) x 17.4cm (width) x 3cm (thickness). With a certificate of guarantee, but no explanatory booklet. I do not have detailed knowledge of this item, so I appreciate your understanding.
