These are cover photos of pamphlets/booklets all published under the "Finbarr" / "Finbarr International" imprint — a small British mail-order press specializing in cheap, saddle-stitched booklets on practical/pulp occultism: talismans, black magic, satanic ritual, grimoires, evocation, and "mind power" self-help. (Worth noting: images 8 and 16 are the same booklet, Gaining Dark Powers by Joseph Etuk.)

What Finbarr is The imprint is run under the name "James Finbarr" (sometimes styled "James Finbarr Cullinan" in promotional copy), who describes himself in his own booklets as a longtime publisher of self-help and esoteric literature, citing a title he put out as early as 1985 and claiming several hundred titles released since. Marketing copy elsewhere calls him a "legendary occult publisher" with decades in the trade. One of his booklets (The Book of Forbidden Knowledge, image 4) even opens with a first-person publisher's note about having sat on the manuscript for 20 years before printing it. Pinterest + 3

Where from / when Bookseller records place the imprint in Great Britain, with individual pamphlets dated as late as 2013, and older catalog copies (advertising leaflets, etc.) turning up from around the 1990s. Other listings date specific Finbarr pamphlets to 1995, 2006, and 2008. Your own photo of The Infernal Magick of the Planetary Pentacles (image 6) has a printed copyright line of 2011. So the operation seems to run continuously from the mid-1980s through at least the mid-2010s — a long-running, low-budget photocopy/print-on-demand outfit rather than a single dated print run. AbeBooks + 2

The "authors" A recurring set of names shows up across dozens of otherwise-unrelated titles in the catalog — Basil Le Croix (elsewhere credited as Basil F. Crouch), Marcus T. Bottomley, Oliver Bowes, Joseph Etuk, Nathan Elkana, Godfrey de Mortain, Graeme D. Brown— a pattern consistent with house pen names rather than a wide roster of independent writers, which is common in this corner of mail-order occult publishing. Scribd

Genre context It's worth distinguishing Finbarr from the more literary/practitioner-oriented occult presses of the same period — e.g. Mandrake of Oxford, founded in 1986 by Mogg Morgan— those aim at serious ceremonial-magic and Thelemic readership, whereas Finbarr's catalog (satanic rites, "winning at all cost," occult manipulation of groups, etc.) sits closer to the older tradition of sensationalist, populist spell-and-talisman pamphlets sold via classified ads. Much of the back catalog is still sold/reprinted today through specialist occult booksellers like Dæmonic Dreams. Wikipedia
