      You can find images of Urbana's "2^11213-1 is prime"
      postmark and IBM's "2^19937-1 is prime" letterhead in Figure
      72 on page 166 of _Mathematical Magic Show_, by Martin
      Gardner, (c) 1977 by Martin Gardner, published by Alfred A.
      Knopf, Inc.

      Hope this helps,
      That bloody top-poster Dan Morenus
