I spent several years collecting/painting humanoid figures per Gary Gygax's descriptions listed in his 1977 1e AD&D Monster Manual. I bought some 1/72 scale Caesar Goblins as they sized up to the right figure size, against a 25mm Human figure. Long story short,
here are some of them, painted brick red, riding Prince August Fantasy Mold Wolves (the PA Goblin Wolf Riders failed to cast properly, so this was a happy compromise). These are a part of my Goblin Army of around 230 figures: multiple Infantry poses; Wolf Riders; Red Box 1/72 scale Goblins on Wargs (technically, they are Orcs, but I painted them as Goblins; the Wargs are a bit small, but I don't care); and some
Molotov Cocktail chuckers riding Giant Bats (Caesar Goblins, Safari Ltc. Fruit Bat toys).
I considered painting some of my Goblins yellow, or orange, the other two colors Gary described them as having, but I wanted to keep the Red Goblins as a mass of troops, so they all got the same color scheme. They are used in my 2e BattleSystem mass battles games. Cheers!
