A front cover for the sf fanzine RUNE #76 in 1987, by the very informal science fiction club "The Minnesota ScientiFiction Society" of the Twin Cities region. DavE Romm was the editor, and he wanted something on the transition of zine production (that was slowly building up speed) from using second-hand office-duplicating machines, to electric typewriters, and computer software word-processing programs, and printouts used for preparing copy for small commercial offset printers, or even files printed directly from home printers or files printed on low-cost xerox-style home printers.

Six representative sf fans are having a meet-up to contact the spirits (and kami) of zine printing to get advice. Amid some noise and visual confusion, they seem to be beginning to get help from local contacts, to make their connection with the 'other side' of zine production. A friendly sounding floppy-disk guide appears. "Are they friendly Spirits?" "Just listen!..."

"Corflu", the very volatile spirit of Correction Fluid, was applied to errors on mimeograph stencils, which were made of a thin layer of flexible wax on a fiber base that was sold as a flexible sheet that would be typed on by a typewriter machine, the type keys (without an ink ribbon) would push the wax out of the way, just enough to let ink get through in the mimeograph printing machine, and appear on a sheet of paper. "Corflu" fluid was colored wax dissolved in a thick solvent that could be applied over the displaced wax in a typing error. The blob of wax would be ready in moments to have the correct letter made with the correct typewriter key. This magical operation (errors that could be corrected!) invoked a near worshipful attitude in some of the fanzine fans. Corfu was a volatile enough spirit, that inhaling it might have some Very Interesting effects. Inhaling corflu is not recommended.

"Hectoplasm" is a reference to "ectoplasm" (historical buzz-word at seances), and "Hectograph" (translating to "100 images"), originally a brand name for one of the first office copying methods. The printing 'machine' was a flat tray of set gelatin, that had been inked using alcohol-soluble dyes transferred from a sheet of paper. One of the earliest dyes used for hectograph was 'aniline purple' (mauve). Hence, a source of some of the earliest home zines, printed in purple ink on white paper, as early as the 1860s.

You may notice that "mythological correctness" was a thing in sf fandom way before other forms of correctness. Since sf fan mythology goes back to the first apparent appearances of the many science fiction universes, that could be a hard act to follow.

The gremlin-like qualities of printing work are represented by funny-animal spirits approximating the appearance of "Froggy" the Spriteling and 'Woolbinkle the BOOse". No real funny animals were satyrized in this cartoon.
