Note on a Possible Eclipse of Jupiter's Second Satellite by the Shadow of the Third

This is not a pulp magazine cover. The submitted image is a page from the Monthly Notices of the Royal Astronomical Society, volume LVI, authored by A. C. D. Crommelin and published in 1896. It reports an observed dimming of Jupiter's moon Io (Satellite II) possibly caused by the shadow of Ganymede (Satellite III), drawing on eyewitness testimony from Fred Jackson of Stoke-on-Trent and heliocentric positional data supplied by Mr. Marth. No cover art, typography, or genre signals are present. A wall label for a pulp-cover exhibition cannot be written from this source.
