Set of 4 dining chairs by Frantisek Jirak, Czechoslovakia, 1950s

Set of 4 dining chairs by frantisek jirak, czechoslovakia, 1950s. Original, unrestored condition, the wood as well as the construction is in very good condition, the chairs are stable, the fiberglass shells are not cracked inside. The upholstery is 'as is' but still useable. Would benefit from reupholstery.
