This is an interesting card, and I don't know what to think- you have very knowledgeable collectors who have been in the hobby for years and know their cards who've seen it in person and say the card is legit.
You have SGC slabbing it, and I know TPG's can make mistakes- but I've come to trust SGC's opinion the most (of TPG's)........
If it is legit, there's no other explanation other than PB blue.
If it is legit, wouldn't that make this rarer than Brown Old Mill, based on known examples?
And, to top it off, I keep hearing Peter's words saying "What if it were done to prove a point"
.....(I don't know if I have that word for word)
And no one is talking about re-backing on this one,,,,
I am surely confused.
, it sure looks legit but for some reason I can't help being skeptical?
Sincerely, Clayton
