StarWars-Figuren has posted card back images of the 3 Walmart exclusive figures coming later this year. And they confirm the VC numeration for them as well as design changes which incorporte the 50th Anniversary timeline as previously seen on the newer Black Series Archive waves. The numbers breakdown as follows:
VC190 Paploo
VC191 Princess Leia (Endor)
VC192 AT-ST Driver
We have also been able to determine the internal code names for each and they are “OVAL”, “OCTAGON” and “CIRCLE” respectively.
