Because these early issues were loosely credited, they are best described as multi-creator anthologies, rather than comics by one writer.
Death Rattle #1 (1972) features stories/art by Tim Boxell, John M. Pound, Richard Corben, and Peter Poplaski; the first volume also includes work associated with Tom Veitch and Mike Vosburg.
Death Rattle #3 (1973), the final issue of the original three-issue series, includes work from Mike Roberts, W. E. Hayden, Tim Boxell, John Pound, Mike Vosburg, and writer Tom Veitch. Veitch and Vosburg are specifically noted as reunited in the issue.
