Here's a Bugbear Chieftain by Jeff Dee, circa 1980. According to the Monster Manual, a chief has "armor class 3, 28-30 hit points, attacking as a 4 hit dice monster, and doing +2 damage". The MM further specifies that bugbears use a range of weapons "from swords to clubs with spikes set in them (morning stars)", fitting with this fellow's sword and morning star. This bugbear wears similar armor (vest & arm pieces) as the one in the main illustration by David Sutherland in the MM. The Chieftain's shield appears wooden, with a knight emblazoned, and slightly damaged - perhaps plundered from a fallen adventurer?
Like the Drow Captain from last week, this art was a design for a mini in the Grenadier Action Art Set Monsters (8002), 1980, although the sword was lowered, and it was retitled "Bugbear Chief", per the MM:

As with the last two pieces in this series, this art work originally surfaced in 2004. The Bugbear Chieftain art was resold on Ebay last November for about $240, along with the written description sheet for the artist to use:
