I briefly maintained a fansite devoted to Big Bang Comics in the mid-00s (OK, that was weird to write). When I wrote to BB editor/writer Gary Carlson to show him the early stages of the project, he wrote me back to tell me that he enjoyed the site. He also had a rather unexpected request.
At the time, the next issue of Big Bang due was the one-shot Ultiman Family #1. As it turned out, Gary wanted to do a riff on those old "reader submitted costume" features like this one showcased at Gone & Forgotten (go read that, really). So, Gary asked me to submit a costume design for Thunder Girl which would be drawn by one of the artists for Big Bang.
Well. As I am sure you remember, I'm not much of an artist. Still, this sounded like a lot of fun! I pulled out some old Supergirl issues of Adventure Comics for reference and went to work on November 12, 2004. I started by mimicking a couple of Art Saaf poses, then moved away from that a bit. I decided I wanted it to look kind of silly, but without too many extraneous details. In the end, after making two or three passes, this was what I sent Gary:

Gary said that was perfect. Flash forward a couple of months and we arrive at the day Ultiman Family #1 came out. In the back part of the book was "Thunder Girl's Fashion Show". And lo and behold, here is one of the costumes drawn by Jeff Austin:Ultiman Family #1. I've had many letters of comment printed over the years, but this is still one of the coolest things ever.
