The collapse is an original lithograph on paper realized by Giuseppe Megna. Hand-signed on the lower right, numbered on the lower left in pencil, edition of 6/80 prints. In very good condition. The artwork represents the collapse through vivid colors, skillfully created, in a well-balanced composition, with mastery in drawing of each detail in the scene. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
