The den houses a series of scrapbooks, compiled by me over well over half a century, preserving newspaper clippings, magazine articles, interviews, movie and product advertisements and other items about things prehistoric, including newspaper comic strips and single-panel cartoons — not so much well-known titles like Alley Oop, B.C., Calvin and Hobbes, The Far Side, Tarzan and The Flintstones, but rather those not generally known for such subject matter, some very obscure or even forgotten today. These are just a few examples of some of those strips and cartoons.
