These beautiful cigarette cards are part of a set entitled “Romance of the Heavens”, issued in 1928 by Wills Cigarettes. (Top and bottom photos were issued in 1929 and have been redone to say “Romance of the Heavens” in the top corner, instead of “Wills Cigarettes”.) I’ve been unable to find larger scans of them (those shown were taken from auction scans, the parts that weren’t watermarked, anyway.)
One seller describes them: “These cards show drawings of the planets and stars; the backs describe how these were understood in the 1920s.” Fortunately an eBay Guide has the details:
