WOW! Recently GMC auctioned off a raw, mid-grade copy of the 67 Spiezio "variation" and there were three separate bidders who bid $1k+ for this card. Can't say the last time I remember this card in mid-grade shape fetching this amount. This card stole the show from the 68 WL McCormick which, while in slightly lower grade, sold for an uncharacteristically low $220 during the same evening.
