Wood, measurements 15.5 x 12 inches and 20x 12 inches for larger picture block
Purchased from a thrift store
What you have are Bamboo carvings made in China in second half of 20th century. They are not antiques. Having said that Chinese art and antiques market is good. I think if you would like to sell them they are interesting for Chinese buyers I believe. Its possible these panels originally came from a cupboard see some examples in
Even so these panels can be sold separately.
My estimation is for the whole set ( 9 pieces ) in good condition with no missing pieces or damage to the carving.
