Series of four bistro chairs

Series of four mismatched bistro chairs. Two of them are of the brand luterma, 1960s (stamp visible under the seat). The other two have slightly different shades and shapes. One of the seats has a small hole, visible in close-up in the photos. The chairs are made of beech wood, patinated with walnut husk and waxed. The whole is in good condition, robust is stable. They present some traces of time that bring them charm and authenticity. I also offer for sale the pair of luterma alone. Seat height 44 cm. "baumann, tuna, fischel".
