I'm having doubts of how well fabric costumes work for 6" scale.
Looks like Mego...
I hope they won't be more than $100 each. Would love to see (and have on my shelf!) lots of seminal Batman renditions throughout Bat's 75 years-- including Kane, Sprang, Adams, Aparo, Mazzuchelli, Miller, Lee, Garcia-Lopez, Jones, Bermejo, Van Sciver, Pope, Capullo. A longshot maybe, but kind of having a 1/12 articulated version of DCD's B&W statues.
