Old School FRP

Seen on r/adnd and r/OSR, a 3D build of the 1979 AD&D White Plume Mountain dungeon by u/Robster3000, including the terraced zoo of charmed monsters, the floating stream, the turnstile, and the rotating funhouse corridor

The escaped human gladiator Neeva wearing a wing-like cloak, in Brom's box art for the first Dark Sun module, DS1: Freedom by David "Zeb" Cook (TSR, 1991)

A druid's sickle is an important tool and a badge of identity (signed "Haggis," which seems to be the signature of John Kirk, from "Druids in AD&D" by MJ Wilson, Australian Realms 2, July 1988)

The Gargun (also called Foulspawn, orcs, or goblins) are covered with coarse fur, but have a reproductive system resembling that of some insects. Each tribe usually has one fertile queen who lays clutches of up to 80 gelatinous eggs. A Gargun lodge has separate chambers for the queen and king, and for the eggs which incubate in a pit of decomposing organic waste. (Hârn by N Robin Crossby, Columbia Games, 1983) This first boxed set introduced the system neutral Hârn campaign setting with a realistic medieval European background and a very different take on orcs.

Brought an AK to a swordfight (Bill Neff cover for Ral Partha's 1986 Fantasy Catalog) -- This picture is still used as the cover for the Chaos Wars rulebook PDFs, with the gun replaced by another crossbow

Knights of Nyrond do battle in the wake of the Greyhawk Wars. Dissenting nobles rebel openly against the ancient authority of King Archbold, while forces of evil lay their own plots in secret. (Eric Hotz, AD&D Greyhawk Adventures supplement WGR4: The Marklands by Carl Sargent, TSR, 1993)

I always assumed this was a swashbuckling goblin. Bob Naismith sculpted some dark elves for Grenadier's Fantasy Warriors line in 1992 that look somewhat similar, with long pointy faces, a long narrow strip of hair, dual weapons with basket hilts, and a mix of mail, plate, and leather.

This could be a good hook for an adventure. Unusual creatures are overrunning the land but the source turns out to be a wizard who has no evil intent. He's just bored and needs a different hobby, or maybe to be set up on a date with the witch in the neighboring valley.

Bonjour, je m'appelle Cthulhu. Où est la bibliothèque? (Ad in Casus Belli 29, 1985, for French language editions of Call of Cthulhu by Jeux Descartes, including the first edition of the classic adventure Masks of Nyarlathotep by Larry DiTillio and Lynn Willis)

Double threat: heavily armored lizardman with magic staff (Chris Achilleos cover art for Warlock 6, "The Fighting Fantasy Magazine," Oct/Nov 1985; originally used as the cover for some 1975 and later printings of the novel Swordships of Scorpio by Alan Burt Akers, a pseudonym of Kenneth Bulmer)

Most of these are from Ral Partha's "1200 AD" line, dated 1979. I added Bishop Odo's wooden club after the Bayeux Tapestry. The single commander on foot is a Ral Partha Imports figure in slightly larger scale, as are a couple of the mounted knights that originally were made by Citadel. One stand of javelin skirmishers are by Old Glory, a bit bigger than Partha but the closest I can get at the moment.

Before they wore the giant Mesopotamian hats, the Chaos Dwarfs were more individually varied and chaotic (sculpted by Alan and Michael Perry, ad in White Dwarf 78, April 1986)
