In this article no 5, Teaparker goes into more detail about the faking of old graphics and designs. He shows 2 pictures of such old trademarks and says that puerh cakes or bricks with such designs are confusing to consumers. It's because these marks are remains from the past and there is no relationship between the previous owners of the trademark and the current ones (unlike famous western brands).
Teaparker further says that he would welcome using old designs on puerh cakes if the tea would match the description on the wrapper. But he even saw a graphic saying zhuan, while the puerh was pressed as a cake! In his experience, the teas that are packaged this way are usually teas with 'problems'. Only a few exceptions can live up to the brand's reputation.
In his 6th article, Teaparker again warns against buying puerh based solely on its wrapping paper. With current advances in printing technology, it's possible to fake anything you want, provided you have just one original. During his research trips to China, he pretends to be a Taiwanese wholesale buyer when he visits factories. He says there are factories where you can place your order for whatever shape of compressed puerh you want with whatever brand and design you want on the wrapper.
