Letterpress printed poster, about 12″×18″, from Anonima Impressori in Bologna, Italy, using wood type and metal type from their collection.
The wood type appears to be a version of ITC Avant Garde Gothic Condensed, cut by Xilografia Italiana circa 1970s, according to the online specimen of the Anonima Impressori collection. In small type the typefaces are identified as Arenzano (Avant Garde Gothic Condensed) and Forma. The specimen of Arenzano is shown on page 5 of the PDF linked on their website, identifying the producer of the wood type as Xilografia Italiana.
In the background is a single large and bold glyph A, taken printed from a yet unidentified geometric (wood) typeface. [It’s probably Semplicità, see comments.—ed.]
The /A on the background definitely looks as one of the woodtype adaptations of Butti’s Semplicità. I think there are some unauthorized, but if I recall correctly Nebiolo had its own in their woodtype catalog.
