The 1980-1990s 501 back patch has many patterns and is interesting.
It differs depending on the factory where it was produced.
The history of such a back patch is as follows.
black and thin letter type
“CARE…” stamp May 1978 6 plants
501-0117 (long length) May 1982 Factory 524
501-0000 (raw denim) February 1986 Factory 515
Printed “CARE…” Nov. 1987 555 Plant
red letter type
Medium-sized characters June 1990 Factory 553
Bold xx added July 1992 546 plant
Bold letters October 1992 552 factory
“CARE…” stamp in thin letters February 1993 552 factory
bold black letter type
Addition of xx August 1997 555 factory
These patterns will be a valuable vintage after another 10 years.
I’mlooking forward to what kind of name it will be called in the future.
