ID help please
Just had breakfast with a friend who was in Kunming on business. When I mentioned tea, he pulled out a cake that had been ceremoniously given to him by a plant scientist there. He'd tried some, and hadn't liked it.

Here are pictures of the wrapper



main info block



and a barely readable pencil notation on the cake



Given the circumstances my friend described, I would have expected this to be something special. When I inspected his cake, it looked (and smelled) much more mature than the 2006 label date or 2005 pencil note would suggest. (-But no taint of wet storage.) I took some home, and found it quite pleasant: mild, appealing flavor and good hui gan. I told my friend that I'll be happy to brew some for him, perhaps more to his taste.

I tried to find more information on the Web, using many variations of the label's spelling. The images (man and horse, old tea tree?) also seem distinctive. But I found nothing.

Can anyone here help to identify brand, factory and composition?

Thanks-

DM
