What is this sticker?
Is it a valid authorization within the hobby?
Dan Mathews has a service that will confirm the piece being original for a fee.
I bought a globe and peeled that off not knowing what it was .. ...
Steve, if you go to Petroliana News Dan listed an auction and the TAC appears in the description on many of the signs posted.
So this tag is from Mathews??
Yes, he also has a partner who's name I can't remember.
I believe if you go to his website and type in the TAC number your item will come and confirm it has been verified as original and show a picture of the item. Someone paid money to get the items with the TAC sticker verified. I would not take those off.
