Fang VS Viper
For the past 10 years fans have known these two Fun World ghost masks by the names 'Fang' and 'Viper' as described on their website. However, an interesting discovery recently came about: the names have been reversed!
Brigitte Sleiertin-Linden, The original designer of what we have been calling 'Fang' disclosed to me that she originally called her mask 'Viper' - and that it was Frank McGovern's mask that was called 'Fang'. I wasn't sure what to make of this, until a new name tag discovery:
This confirmed Brigitte was correct! What we've been calling 'Fang' was originally called 'Viper'! Frank, who designed the other snake-like mask agreed: Brigitte's design was originally called Viper until his joined the catalog. He says he use to refer to his mask as the 'Fang' ghost!
At some point Fun World flipped the names, probably for the Dead by Daylight video game's "Viper Face" character.
