The Who's Who verifies, as do Mike Kooiman and Jim Amash in the Quality Companion, that Kiefer, not only created this feature, but did the art for it through the strip's entire run. However, the Who's Who does not specify a writer for the strip (although Kiefer is usually considered to have written it) so a ? has been placed after his name as writer.
Drew Allen is Kiefer's pen-name used on the strip.
The Who's Who lists no writer for this strip. Paul Gustavson created the Spider, so it is generally assumed he wrote it.
Runs on the bottom half of each Jane Arden page.
Richard Grey Jr. eventually assumes the identity of Senator Thomas Wright.
