Review for LEGO set 3343 2 Battle Droids and Command Officer from Brickset
“The bases also feature a very nice engraved Star Wars logo in front of the studs and the ability to hold a card in the back. So you also get 3 cards, all different, that are sort of like baseball cards for each droid, although they are maybe half the size of baseball cards.”
