If there is somewhere I can upload the 13 MB AI file, no problem.
I can give you a little instruction on how I got the results I did.
1. I used the original jpg files posted on this page. I used Photoshop to resize them to 1000% using Bicubic scaling.
2. Then I imported the image into Flash and scaled the image down (using shift to hold proportion) so it will fit the screen. Then I selected the image and traced using the following options...
Color threshold: 50
Minimum area: 8 pixels
Curve fit: Normal
Corner threshold: Normal
3. Now select the white areas around the character and hit delete on the keyboard to remove it.
4. I had to patch up some places that were white and were removed with the background, so I use the pen tool to close up the gap and fill it with white again.
That's it, and probably the best results I will ever get without tracing by hand.
I'm still not sure if I'll try and print this yet.
