I can't seem to find any proper picture either. I think the easiest way is to get a Samuel Adams bottle, a camera with a macro function and just take a picture of it. Chucara can do that for you - just send him the beer bottle (should not be opened, or it wouldn't get through customs), and I'm sure he can make a script that can take the image and send it to you.
Oh, and you should probably send at least a six pack, in case the first one fails, or is damaged during shipping. *nods*
