According to the seller, this is an “original” Side By Side tee. If he means, “originally printed by Lost And Found Records” then he would be correct.
Judging from this seller’s other auctions, I would guess the seller isn’t as steeped in hardcore tshirtology as the staff of TeeTillDeath.com. Of course, we don’t expect all sellers to have accumulated as much worthless tee knowledge as us either.
Fear not, I plan on alerting the seller to their mistake. I just found it amusing.
