If it's spam it should be pretty obvious, as they're typically so poorly made. I get them all the time. They don't even put any effort into them to make them look official.
Nobody got theirs from Sideshow. HT sends SS a figure the fastest way possible so they can get their unboxing video up before anyone else. The actual shipments are on a 4-7 week boat ride. 😒
And SS has to delay the figure because, obviously, they don't have it yet.
Amazing work. Some of you need to stop critizing Mars for taking a long time with releases. Their end result is well worth the wait. Plus who else would have given us this version of '89 Joker and the '66 version?
