Jada Toys, makers of the Batman v Superman: Dawn of Justice Metal Figs, released wave 1 of a series of miniature figurines called Nano Metalfigs. This is a Superman diecast figurine that is number DC3 in the series and, according to the art on the card, the figurine is based on the “rebirth” universe.
To me, these diecast figurines are very reminiscent of the Ertl versions that were released back in 1989.
Within this first wave of DC Comics characters are a “Classic TV Series Batman” (DC13), and another Superman (DC15). The checklist of the figurines on the back of the card, which go from DC1 to DC34, is curiously missing DC14, DC21, and DC24 through DC31.
