Cover of Casabella, N. 511, March 1985, 20th Century, graphic, 31 x 28 cm

Whole artwork view. Blue headline on a gray background above a graphic composition representing twelve black and white sketches by German architect Oswald Mathias Ungers; the drawings, drawn by the studies of Ungers upon his project for the Frankfurt Fair Skyscraper, illustrate the formal exploration of the idea that gradually comes to involve the joint of vertical elements placed upon a triangular base; from the tall slab of the first project on top left one comes to more and more complex structures, with a holed surface, until the definitive design of a tall central body, in connection with two other, until the almost final design of a central tall element attached to two lower ones, which features a square hole in the middle of them.
