Bard Doll was implemented into the game not a long time ago - with a patch 12.31.954. It presents a bard known from TibiaRia's logo:
TibiaRia.com didn't announce any "Fansite Item Contest", the creator of Bard Doll is Elfo Fantasma, founder and admin of the fansite.
I asked Elfo about the current owners:
Currently there are only 3 owners, me, Kadazin who is the artist of tibiaria and Helvans who updated and implemented contents to the website.
Now players can win Bard Doll in their "The MemeKing Contest" as a yearly reward.
