CLARIFICATION: It looks like we will run all three of these designs (four counting Rudy on a non-black shirt), but your feedback can help us get quantities right so we don't run out of your favorite! Thanks
Here are some images of the art we are looking to use for the 2009 show shirts.
Bobby Tribble has again come through with a great shirt design celebrating our 13th show!

We're thinking this design works best on a black shirt, but here are some other possibilities:

Rich from ThisOldGame.com put together a bunch of great designs as well. Here are the two we currently have in mind to use:
First, a vector themed design - possibly to be run in fluorescent inks:
UPDATE: Rich took some action on feedback, here is a revised version!

And one based on Death Race:
UPDATE: Here is Rich's revision on the D.R. design, with some refinements and a dash of color:

I suspect both of Rich's designs work best on black shirts.
We understand that those looking for a pinball themed shirt may not find these two designs on the top of their list, but the thought is the different styles will appeal to different people.
For all designs, we plan to run the designs large on the back, with our oval logo small on the front.
We will probably also run some of Bobby's design on some other color (ash?) for those who don't want black, and we could probably put the Death Race printed in black on an ash or white shirt.
We can make a few special orders (design printed on the front for people with long hair, XLT size or whatever.) If you let us know what you need, we'll try. Mail
info@caextreme.org with specific requests, just post here with general feedback.
We are also considering a limited run of premium shirts on black button down work style shirts.
Let us know what you think so we can try to get it as right as possible!
