The Absinthe Fairy

This image is called 'The Absinthe Fairy'. I produced it for an on-line art challenge in 2009. The whole process of its creation was documented as the challenge required you to do that. The image is MINE. I created it without reference or source other than the obvious inspiration. I am currently seeing this image all over the internet, on sites such as Etsy, EBay, Cafe Press etc listed as 'vintage', placed on various items that vendors are selling, from jewellery to bedding to mugs. They are infringing copyright. It's NOT vintage, it is 4 years old. It has been licensed out ONCE to the writer Christopher Moore with changes made to it to suit his requirements. The watermark is ugly isn't it? Wouldn't it be a shame if everything an artist posts has to have that or similar through it?
