Howdy, y'all!

I recently received the following illustrations from Jim Holloway and I'm trying to figure out what product that they were used in. The first looks familiar to me, but as of yet I haven't been able to id the module/mag it was used in. I think the other three were used in a "pick-a-path" type of adventure book, but I really have no clue at this point.

So, I thought I'd ask the Collective if any of the illustrations look familiar! Any help would be greatly appreciated! Thanks!
