Square pot cover in bamboo

This beautiful bamboo pot cover can receive a very large plant. Indeed, it is very large, deep and quite heavy. He is at least 20 years old and probably older, it is difficult for me to date him. It is in good structural condition, still very solid, the diagonal bamboo blades are all there and in good condition, but it does not hide the patina due to years of use: marks and various stains, some of origin probably. I cleaned it thoroughly and put a light coat of varnish on the outer side to even out the hue. It is a square of 60 cm side and 60 cm high. It must weigh between 10 and 15 kg. My shadow slipped on the first photo (the one cropped), so probably that the clipping will miss a tiny piece of the foot in the foreground, but in reality, the foot is obviously whole!.
