Old service trolley from the 60s

On a tray available / magnificent and very practical service trolley on wheels, formica and gold metal, 60s/70s. I couldn't wait to show it to you, because if I adore them for their obvious sign of another time, this one has two or three interesting particularities. The first, a first removable tray which fits on the upper tray. The second, the upper tray is also removable and also heated. Perfect for big talkers who let dishes cool. The third, the cart folds to save space. It's quite rare and I love this system. We are always surprised. Very good condition, some imperfections but nothing remarkable. Unusual piece that fits into beautiful brightened decorations. Dimensions h 72 cm d 59 cm l 73 cm.
