Thrills & Chills was a kids horror magazine published by Scholastic books from 1994 through 1996. I can’t say much about the quality because I’ve only seen the covers and a handful of interior pages, but the series is historical now, if for no other reason than that Earl Norem was a regular illustrator. If you’re new to Norem, start here.
The pieces above are all originals and have sold on eBay over the last few years.
