Saggi di astronomia popolare, 1911, a. 1, f. 02
An Italian popular astronomy booklet of 1911, issued by the Società Urania and the Turin astronomical observatory, with Giovanni Boccardi among its contributors, aimed at general readers interested in the sky. Its pictures are grainy grey halftone plates: a rotated page of a long vertical strip with dark spiky, flame-like forms against a pale ground, and two circular framed images of soft, smoky swirls and curling tendrils captioned with a date from October 1909, which a designer could draw on for abstract, organic textures and vortex motifs.
