This page was created by a deleted user who was accused of making false copyright claims:
The image was used on TONMO.com's "giant and colossal squid fact sheet" earlier than 1/4/07 so it seems likely that the claim of ownership is entirely fabricated. I am going to confirm the source, artist, and attribution of the image with Dr. O'Shea, but it may need to be removed, and almost certainly needs a change in attribution. The current version of the source document is here:
http://www.tonmo.com/science/public/giantsquidfacts.php
the internet archive from July 2003 shows the image:

More information forthcoming.
