its 70's as far as i remember.

BAD RELIGION. last year i went see their gig in japan. their are my first band i saw in live. and bad religion is my most favorite. their are #1 punk(melodic hard core, that we call here) band ever.

i guess both of them are from 80's. first one is not exactly same as 80's CP's tag i know, it slightly different. i have one pacific collegiate tee from 70's. it has completely different tag from 80's. and still it could be 70's, there are tons of secret of vintage tee.
