I wasn’t at NYCC so I can’t say for sure, but I would imagine if anyone got a close enough look they would be able to tell for certain if the figure in question is a production piece or a custom. My guess is the pink haired Mighty Mugg in the photo above is a customized White Blank Mighty Mugg, especially since it’s standing next to a packaged White Blank Mighty Mugg. But you just never know!
