I was asked to remove some pictures by their Author, here my public Answer:
This Tumblr is driven by community submitted pictures, as far as the artist is known he will be named. If not submitted in the picture submit It`s not possible to relink back to all original authors. I`m a professional drawer by myself and can you just give the tip to include a © or name into the picture before you publish it. Internet today and especialy tumblr and pinterest are for the most users a copy & paste world. So many submits and many I refuse to post here because they contain © notice. Those which don`t will be posted until I receive a removal request. So I will delete your pictures then because I can not proofe that you are the legit author of them so in future, as I said, best put in a url into the picture.
