I have set up a "print on demand" store for for Tee shirts and stuff here ...
Eurosport US Store - Printfection.com
I have researched several of the apparel Print On Demand (POD) places and Printastic has the best reputation for high quality products as well as high quality customer service. The shirts I have chosen are Hanes Cool-Dri which are moisture wicking modern fabric short sleeve Tees and also 100% organic cotton long sleeve tees. There are mugs and steins as well. I have tried to make the prices reasonable and to this end I am adding only $5 per tee for my efforts, the rest is for the printers.
Printastic uses state of the art DTG "Direct to garment" screener/printers that are super high quality and run $200k a piece, they have eight of them total in three locations across the country.
In other news, I have created and am currently waiting on the samples of a calendar featuring the illustrations that you have seen on here. It will be a 12 month 2012 calendar featuring a different illustration each month and one on the cover for a baker's dozen. I have put all of the American Le Mans series races on the calendar as well as the Le Mans Test day and Le Mans dates for your convenience. I will let you know the details of this when I have received the samples.
Also as I promised I will begin selling limited edition prints around the first of the year. The art will be more expensive due to the high quality of the output and of course you will want to have it framed so if you cannot swing the cost of a limited edition print for the wall then you can have a ball cap or calendar to enjoy.
