Mario bellini table

This set of four white fiberglass "Quattro Gatti" tables was designed by Mario Bellini in the 1960s for C&B Italia and manufactured in Italy. C&B Italia is the predecessor of B&B Italia. The design is minimalist, practical and very versatile. The small tables can be placed individually, inside each other or on top of each other to form a 92 cm tower. Each table is marked at the bottom as pictured. Dimensions: Table 1: 52 × 52 × 25.5 cm Table 2: 50 × 50 × 24.5 cm Table 3: 48 × 48 × 23.5 cm Table 4: 46 × 46 × 22.5 cm I'm missing 2 tables and one is slightly damaged (see photo)
