I could hand screen print this monochrome image of Churchill http://yfrog.com/62churchillxj (or similar) which I have generated from a digital photograph (I could use any photograph you like) onto a 100% organic cotton T-shirt in your choice of colour & size.
I use non-toxic fabric ink which is fixed using heat, making it resistant to machine washing at 40 ° C, dry cleaning & ironing on a cotton setting.
You can see examples of prints I have made from other photographs here http://maxandmollydesigns.wordpress.com/tag/design/ on my blog.
I donate 5% of my profits to my local greyhound rescue charity.
