Here are two minis from my collection.
I doubt I painted the drider. I did re-glue his crossbow on, but otherwise, he's as-traded-for, probably from Jay A. back in elementary school or junior high. He's pretty intact, if only because I never use driders so his job is to sit in a padded desk drawer for decades on end and do nothing.
The backpack on the drider is a nice touch. It's nice that he's got some actual gear. And a backup sword over his back. The color scheme is good.
The wizard is odd. I definitely painted him - I can tell because he's colored with no primer using blue enamel paints. I had some enamel paints when I was a kid. In fact I still have the set because it nestles nicely in the back of a drawer where nothing else fits and acts to backstop my assembled/painted Ogre garage.
I remember these guys coming in a four pack either painted or unpainted. I have no idea who the manufacturer is. I'm certain I got him and a few other wizards - long since traded, lost, or destroyed - at a Jamesway out in western NJ. Same place I got a lot of my very early gaming stuff. How he lost his arm, I don't know. I'd love to find out more about that mini. He's pretty cool - if he was intact I'd paint him. I'm thinking of restoring him somehow, but I always get a little worried about digging holes in lead. In any case, he's got some unclear markings on the bottom of the base including a "G" and an "H" but I can't get a clear shot of them with the camera and lighting at home.
Editing later: Thank you Chris Katulik for pretty much instantly identifying the wizard as a Mike Carr Heritage Series mini:
There he is on the right, and the other guys are definitely familiar. I'm sure I got the lot in the same blister.
Yet more bits from a gamer who never seemed to keep anything intact but didn't chuck anything away, either.
