This is my sketch for the starship in 82 Eridani. It is described in the story as looking like a 16 penny nail flying through space head-first.
You can see some of my notes and adjustments made on the fly. You might also note that this is drawn on the back of a 7th grade History worksheet. A lot of those have been used as scratch paper for story details over the years.

Wes, is there a larger version of this pic? I can’t make out the detail, even with my specs! 🙂
I will post a larger one.
