D. Hands (or Diverse Hands) was a pseudonym used at Marvel Comics to simply refer to a collection of artists that worked on an issue in some small part, but didn't receive full credit for it. The first usage at Marvel was in July 1978 on The Avengers, and continued on every so often through to the late 1980s. It was used on their Star Trek run in one issue, #13: "All the Infinite Ways".
