Vintage XL extendable table by Thonet with beautiful wear and tear 1970s

Beautiful table with great colour and wear and tear. It shows a lot of character and warmth. Because it’s extendable you can sit at it with four, six or ten people easily. Especially because the table is also wide. Please note the 1950’s Italian styled architecture but I think it’s designed in the 1970’s. By whom I don’t know. The Teak wooden finish at the bottom shows that Thonet, the manufacturer of the table designed a quality piece. It’s signed but the designer is unknown. Beech and Teak wood. Extremely rare. H x w x d 73 x 110-170-230 x 110 cm 28,7 x 43,3-66,9-90,6 x 43,3 inch.
