I've got some of these cakes here but the vendor only told me they were about 10 years old. I noticed that each year the font style and spacing on the wrapper can slightly change, also on the nèi piào.
So is it possible for someone to say this design is exactly from 2001/02/03/04 etc?
One of the intentionally aged teas, Pu-Erh has a loyal following.
actually, an image from skip4tea is similar
I have a 2009 CNNP 7572 and this neifei looks very similar, including the mistakes such as "world--wide fame. through" which is exactly the same on mine. The block justification in yours looks like an older word processor to me because it divides words in odd places that mine has corrected, likely due to a smarter, updated word processing program.
