Starlog did three impressive spaceship blueprints for Anderson subjects, but only did one other print, perhaps to avoid licensing issues.
The Eagle print was a pull-out section that unfolded; it was later sold separately by Starlog. The Hawk was printed across two standard pages. The Altares print was a fold-out page.
The Eagle and Hawk prints were by Geoffrey Mandel (no relation to ITC executive Abe Mandell), who would also draw Starlog's Moonbase Alpha Technical Notebook (1977). Mandel had previously worked in Star Trek fanzines, and would later become a graphic artist on several Star Trek series, as well as many series including Mad Men and Veep.
The Altares print was drawn by UK artist Stephen Corbett.
This Eagle article and blueprints appeared in Starlog 7 (August 1977). This was the Star Wars issue (with a striking photo cover); there were no more artwork covers.
The Hawk article and blueprints appeared in Starlog 32 (March 1980)
The Altares article and blueprints appeared in Starlog 58 (May 1982)
