Von Schweikert lettering rubbed off?

Has anyone else seen the writing on the back of a VR4jr missing? The lettering I am refering to is on/around the rear firing tweeter and around the binding posts. Alot of the words in white lettering are rubbed off.
Is this common?
maybe the person who sold it to you didn't want you to know that they were made in China?
I don't think that was the issue....I bought them in Hong Kong, from a Chinese dealer. The lettering is just partly removed around the ambience driver adjustment and near the binding posts. It is not deliberatley obscured, and a dealer wouldn't deface a speaker unless he was.......a bit slow on the uptake.
I was just curious if others have had this problem.
