Vintage T-Shirt Forum & Community Authentication Appraisals

Harley Davidson (HD) is very strict about copyright issues, when a 2010 shirt wants to be printed in 1996, it is likely that one side will be printed in 1996 and the other side will be printed in 2010.
So let me ask, is there a case of t-shirts: The front and back are both printed with the year 1996, the neck tag is from the 90s, one thread but it was printed in the 2000s?
I FIND IT VERY UNREASONABLE

Not sure I fully understand, but remember 1996 is the date the artwork was copywritten, it's not necessarily the date the shirt was printed.

And it wouldn't surprise me if there was a 1996 art on one side and one from 2010 on the other.
