Felt bottom weighted pieces (bakelite?) with 12" x 12" wooden board. This set has been in my family since the 1950s and does not include the original box. The board does not fold. Please note 2nd to final photo, surface crack on the back of the board, is not deep and does not impair the function of the board. Final photo shows four pieces with flawed felt on the bottom - the remaining pieces are fine.
