This is an old Ral Partha frost giant. It’s quite different than Boerogg. This one is from before things got quite so cartoony in D&D art. Early versions of D&D had giants conceptualized as extra large humans, with frost giants modeled after vikings, like this guy.
The snow is washed out in these photos, sorry. But that’s just as well; I didn’t get he snow mixture quite right here. It was a little too thick, so it didn’t self-level well and had some bubbles in it that show in real life.
