Just found another set! I'm a long time fan of Inna, so I know her quite well and can recognize her anywhere - so I'm 100% certain it is her.
The set is from Met-Art, by Voronin and it's named "Presenting Inna". However, she doesn't appear with her usual "Inna F" name there, but instead "Inna G". It's the only set under that name.
It's not really a "new" set. It's actually an update from Nov. 2005. But because of Met-Art's lousy cataloguing and mixup with the model names, nobody seems to have noticed it... I just found it yesterday! From what I can see, nobody here knew about that set either -- so should be good news for some. :)
