"TEENAGE MUTANT NINJA TURTLES : OUT OF THE SHADOWS" // SDCC "Michelangelo" Collector's card (( 2013 ))
approx. 6" x 4"
-->> Roughly postcard size, each Turtle collector card was available at the IDW boot, one each day with leftovers from the day prior being available with the new ones.
The new TMNT video games were lightly promoted; with TMNT:OOTS being mainly trumpeted by IDW themselves as this is a more mature title than the new game based directly on the show. Those were more readily ( but again lightly ) promoted by Nickelodeon themselves at Nick's booth and at the Nick Turtle animation panel.
So far i've only been able to obtain Mike & Don's cards.
