Gasholders, this one almost 130,000 cubic meters, ridiculous in comparison with the great work of Mario Sironi, 1943. The drawing is part of a series of 6 works created on the occasion of the decommissioning of the Gas Works in Bovisa. Detail of the large helical gasholder of the Gas Works, which is ironically linked to the one depicted by Mario Sironi in the work "Il Gasometro" (1943).
