Announced earlier today on the official Topps Star Wars page on Facebook is an exclusive, oversized Boba Fett card. It's an SDCC 2015 exclusive.
Their announcement revealed it's part of a set of larger cards:
"Topps will have 10 sets of oversized cards featuring classic Star Wars characters on iconic Topps designs. Find us at Booth 2913-J."
It's unclear if this oversized card is part of the same 10" x 14" series that Topps recently marketed as wall art. Those prints retail for $99.
(Helmet nod to The Collectors Cantina for the heads up about this announcement.)
