Rather big ceramic vase, unknown signuture

Hi, first post so I hope im doing this right now.

This large ceramic vase has an unknown signuture to me.
It measures 25cm in hight and its about 21cm wide.

My guess is that it maybe comes from Denmark due to the colour of the ceramic. Ivé seen similar colours before on the ceramic.
It also looks like a bird on one side, or maybe its just me.

My vase has been posted on another forum, with very knowable people, but we got stuck.
What we maybe could tell is that the signuture maybe could be red as CG GG CC or something.

Any clues, ideéss and help are very much appreciated. I love to hate theese UFO:s =)
